A barcode is a type of machine-readable code which stores information about various items in the form of lines and spaces arranged in a pattern. Barcodes are made up of a series of parallel bars that are used to encode data. These bars make up what is called a "barcode" or "barcode symbol" which can be read by a barcode scanner (sometimes just called a "scanner"). All barcodes have four parts:
Barcodes are the most efficient way to identify products in a retail environment. Every product has a barcode that is unique and can be scanned with a scanner for inventory control or for price verification. Nowadays, barcodes are not just used as an efficient way of identifying products in a retail environment, they have become an important aspect of our everyday life because they are used to store information electronically and manage consumer identities.
In this article, we are going to compare two popular barcode libraries:
Both of these libraries can be used for the generation and recognition of barcodes, provide support for all dot net frameworks, and allow you to save the barcode images.
We will look at how to generate a barcode in C# .NET with the IronBarcode library by using an example. We will see how easy it is to create a barcode, as well as how to style our barcode and then export it using IronBarocde.
Open Visual Studio, and then go to the file menu. Select new project, and then select Console Application/Windows Forms/WPF Application. IronBarcode can be used on all types of applications. Also, you can use apps such as Webform/MVC/MVC Core.
Enter the project name and select the file path in the appropriate text box. Then, click the Create button and select the required .NET Framework. The project will now be generated with the structure for the selected application, and, if you have selected the console application, it will open the program.cs file where you can enter the code and build/run the application.
The IronBarcode Library can be downloaded and installed in four ways:
These are:
The Visual Studio software provides the NuGet Package manager option to install the package directly to the solution. The below screenshot shows how to open the NuGet Package Manager.
It provides the search box to show the list of the packages from the NuGet website. In the package manager, we need to search for the keyword "Barcode", as in the screenshot below:
From the above image, we will get the list of the related search results. We need to select the required option to install the package to the solution.
In Visual Studio tools, go to Tools-> NuGet Package manager -> Package manager console
Enter the following line in the console tab:
Install-Package BarCode
Now the package will download/install to the current project and be ready to use.
The third way is to download the package directly from the website.
Click the link to download the latest package from the website. After the download, follow the steps below to add the package to the project.
The first thing we need to do is install the Iron Barcode library, adding barcode functionality to the .NET framework. We can do this using our NuGet package or by downloading the .NET Barcode DLL.
Install-Package BarCode
In the following example we can see that a barcode can be written containing numerical or text content using only a couple of lines of code with IronBarcode.
// Generate a Simple BarCode image and save as PNG
//using IronBarCode;
GeneratedBarcode MyBarCode = IronBarCode.BarcodeWriter.CreateBarcode("https://ironsoftware.com/csharp/barcode", BarcodeWriterEncoding.Code128);
MyBarCode.SaveAsPng("MyBarCode.png");
// This line opens the image in your default image viewer
System.Diagnostics.Process.Start("MyBarCode.png");
// Generate a Simple BarCode image and save as PNG
//using IronBarCode;
GeneratedBarcode MyBarCode = IronBarCode.BarcodeWriter.CreateBarcode("https://ironsoftware.com/csharp/barcode", BarcodeWriterEncoding.Code128);
MyBarCode.SaveAsPng("MyBarCode.png");
// This line opens the image in your default image viewer
System.Diagnostics.Process.Start("MyBarCode.png");
' Generate a Simple BarCode image and save as PNG
'using IronBarCode;
Dim MyBarCode As GeneratedBarcode = IronBarCode.BarcodeWriter.CreateBarcode("https://ironsoftware.com/csharp/barcode", BarcodeWriterEncoding.Code128)
MyBarCode.SaveAsPng("MyBarCode.png")
' This line opens the image in your default image viewer
System.Diagnostics.Process.Start("MyBarCode.png")
We first create the barcode by specifying its value, and the barcode format we will be using is from the IronBarCode.BarcodeWriterEncoding Enum. We can then choose to save as an image, or as a System.Drawing.Image, or as a Bitmap object. That's all the code it takes! The final line of code simply opens the barcode PNG in the example so that you can see it with your own eyes.
Although the previous example was effective, in the real world we may wish to do more. In the following example, we may add annotations to the barcode, set the font, display its value below it, add margins, change the barcode color, and then save it, all quite simply in C#. We can also choose to export to HTML or PDF instead of an image, if that is more appropriate for our application.
//using IronBarCode;
//using System.Drawing;
// Styling a QR code and adding annotation text
var MyBarCode = IronBarCode.BarcodeWriter.CreateBarcode("https://ironsoftware.com/csharp/barcode", BarcodeWriterEncoding.QRCode);
MyBarCode.AddAnnotationTextAboveBarcode("Product URL:");
MyBarCode.AddBarcodeValueTextBelowBarcode();
MyBarCode.SetMargins(100);
MyBarCode.ChangeBarCodeColor(Color.Purple);
// Save as HTML
MyBarCode.SaveAsHtmlFile("MyBarCode.html");
//using IronBarCode;
//using System.Drawing;
// Styling a QR code and adding annotation text
var MyBarCode = IronBarCode.BarcodeWriter.CreateBarcode("https://ironsoftware.com/csharp/barcode", BarcodeWriterEncoding.QRCode);
MyBarCode.AddAnnotationTextAboveBarcode("Product URL:");
MyBarCode.AddBarcodeValueTextBelowBarcode();
MyBarCode.SetMargins(100);
MyBarCode.ChangeBarCodeColor(Color.Purple);
// Save as HTML
MyBarCode.SaveAsHtmlFile("MyBarCode.html");
'using IronBarCode;
'using System.Drawing;
' Styling a QR code and adding annotation text
Dim MyBarCode = IronBarCode.BarcodeWriter.CreateBarcode("https://ironsoftware.com/csharp/barcode", BarcodeWriterEncoding.QRCode)
MyBarCode.AddAnnotationTextAboveBarcode("Product URL:")
MyBarCode.AddBarcodeValueTextBelowBarcode()
MyBarCode.SetMargins(100)
MyBarCode.ChangeBarCodeColor(Color.Purple)
' Save as HTML
MyBarCode.SaveAsHtmlFile("MyBarCode.html")
The code should be self-explanatory, but if it is not, I encourage you to read the GeneratedBarcode class documentation within the API Reference.
Reading a barcode or QR code in .NET is incredibly easy using the IronBarcode class library with .NET Barcode Reader. In our first example, we can see how to read this barcode with one line of code.
Barcode Image to be Scanned with C#
We can extract its value, its image, its encoding type, its binary data (if any), and we can then output that to the console.
using IronBarCode;
using System;
BarcodeResult Result = BarcodeReader.QuicklyReadOneBarcode("GetStarted.png");
if (Result !=null && Result.Text == "https://ironsoftware.com/csharp/barcode/")
{
Console.WriteLine("GetStarted was a success. Read Value: " + Result.Text);
}
using IronBarCode;
using System;
BarcodeResult Result = BarcodeReader.QuicklyReadOneBarcode("GetStarted.png");
if (Result !=null && Result.Text == "https://ironsoftware.com/csharp/barcode/")
{
Console.WriteLine("GetStarted was a success. Read Value: " + Result.Text);
}
Imports IronBarCode
Imports System
Private Result As BarcodeResult = BarcodeReader.QuicklyReadOneBarcode("GetStarted.png")
If Result IsNot Nothing AndAlso Result.Text = "https://ironsoftware.com/csharp/barcode/" Then
Console.WriteLine("GetStarted was a success. Read Value: " & Result.Text)
End If
We will add our TryHarder variable to the QuicklyReadOneBarcode method. This makes it try harder, literally taking more time, but scanning deeper for a QR code that might be obscured, corrupted, or at a skewed angle.
BarcodeResult Result = BarcodeReader.QuicklyReadOneBarcode("TryHarderQR.png", BarcodeEncoding.QRCode | BarcodeEncoding.Code128 , true);
BarcodeResult Result = BarcodeReader.QuicklyReadOneBarcode("TryHarderQR.png", BarcodeEncoding.QRCode | BarcodeEncoding.Code128 , true);
Dim Result As BarcodeResult = BarcodeReader.QuicklyReadOneBarcode("TryHarderQR.png", BarcodeEncoding.QRCode Or BarcodeEncoding.Code128, True)
It can now read this skewed QR Code:
Scanning a QR code rotated through 45 degrees with C#
You will see that we can specify the barcode encoding(s) that we are looking for or specify multiple formats. Doing so greatly improves barcode reading performance and accuracy. The pipe character or 'Bitwise OR' is used to specify multiple formats simultaneously. The same can be achieved, but with a higher degree of specificity, if we move forwards to using the visual method or the BarcodeReader.ReadASingleBarcode method component mode.
In real-world use cases, we may wish to read barcodes that are not perfect screenshots. They may be imperfect images, scans, or photographs, and contain digital noise or be skewed. With most conventional open source .net barcode generators and reader libraries, this would be impossible. However, this Barcodes Reader in C# makes it incredibly straightforward. We will look at the TryHarder
method of QuicklyReadOneBarcode
. This single parameter causes Iron Barcode to try to de-skew and read barcodes from imperfect digital samples.
We will set the specific barcode rotation correction and barcode image correction to correct for the digital noise, as well as the skew, perspective and rotation that we might reasonably expect from a cellphone camera.

using IronBarCode;
using System;
using System.Drawing;
var PhotoResult = BarcodeReader.ReadASingleBarcode("Photo.png", BarcodeEncoding.Code128, BarcodeReader.BarcodeRotationCorrection.Medium, BarcodeReader.BarcodeImageCorrection.DeepCleanPixels);
string Value = PhotoResult.Value;
System.Drawing.Bitmap Img = PhotoResult.BarcodeImage;
BarcodeEncoding BarcodeType = PhotoResult.BarcodeType;
byte [] Binary = PhotoResult.BinaryValue;
Console.WriteLine(PhotoResult.Value);
using IronBarCode;
using System;
using System.Drawing;
var PhotoResult = BarcodeReader.ReadASingleBarcode("Photo.png", BarcodeEncoding.Code128, BarcodeReader.BarcodeRotationCorrection.Medium, BarcodeReader.BarcodeImageCorrection.DeepCleanPixels);
string Value = PhotoResult.Value;
System.Drawing.Bitmap Img = PhotoResult.BarcodeImage;
BarcodeEncoding BarcodeType = PhotoResult.BarcodeType;
byte [] Binary = PhotoResult.BinaryValue;
Console.WriteLine(PhotoResult.Value);
Imports IronBarCode
Imports System
Imports System.Drawing
Private PhotoResult = BarcodeReader.ReadASingleBarcode("Photo.png", BarcodeEncoding.Code128, BarcodeReader.BarcodeRotationCorrection.Medium, BarcodeReader.BarcodeImageCorrection.DeepCleanPixels)
Private Value As String = PhotoResult.Value
Private Img As System.Drawing.Bitmap = PhotoResult.BarcodeImage
Private BarcodeType As BarcodeEncoding = PhotoResult.BarcodeType
Private Binary() As Byte = PhotoResult.BinaryValue
Console.WriteLine(PhotoResult.Value)
In our final example, we will see that we can create, style, and export a barcode with a single line of code. IronBarcode implements an optional fluent API similar to System. Linq. By chaining method calls to method calls to method calls, we first create a barcode, then set its margins, then export it to Bitmap in a single line. This can be very convenient and make code easier to read.
Free Spire.Barcode for .NET is a free and professional barcode API specially designed for .NET developers (C#, VB.NET, ASP.NET) to generate and read 1D & 2D barcodes. Developers and programmers can use Spire.BarCode to add enterprise-level barcode formats to their .net applications, asp.net Winforms, and Web Service quickly, net applications asp.net Winforms, and easily. Free Spire.Barcode for .NET provides a very easy way to integrate barcode processing. spire create, read 1D & 2D barcode, Spire.BarCode supports variable common image formats, such as Bitmap, JPG, PNG, EMF, TIFF, GIF, and WMF. It also provides support for QR codes.
The first thing we need to do is install the Spire library, adding barcode functionality to the .NET framework. We can do this by using the NuGet package. As we did in the case of IronBarcode, the process is the same — follow the same steps and just type "Spire barcode" and add the packages to a project.
The library provides methods that are used to create barcode images. It is an overloaded method. In this part I list the definitions of the methods. These methods will be used in the code to test the performance of the library
using Spire.Barcode;
using System.Drawing;

{
BarcodeSettings settings = new BarcodeSettings();
settings.Type = BarCodeType.QRCode;
settings.Data = "Hello world";
settings.Data2D = "Hello 123456789";
settings.QRCodeDataMode = QRCodeDataMode.AlphaNumber;
settings.X = 1.0f;
settings.QRCodeECL = QRCodeECL.H;
BarCodeGenerator generator = new BarCodeGenerator(settings);
Image image = generator.GenerateImage();
image.Save("QRCode.png");
}
}
}

settings.QRCodeDataMode = QRCodeDataMode.AlphaNumber;
settings.X = 1.0f;
settings.QRCodeECL = QRCodeECL.H;
BarCodeGenerator generator = new BarCodeGenerator(settings);
Image image = generator.GenerateImage();
image.Save("QRCode.png");
}
}
}

//Generate the barcode based on the this.barCodeControl1
BarCodeGenerator generator = new BarCodeGenerator(this.barCodeControl1);
Image barcode = generator.GenerateImage();
//save the barcode as an image

There are two import classes — BarCodeControl and BarCodeGenerator in this method. BarCodeControl stores information about barcodes. BarCodeGenerator is the class to generate barcode images. Its constructor takes one parameter — a BarCodeControl instance. It has a method called GenerateImage() whose return value is the Image object to generate an image.
The barcode scanner is the class to scan barcode images. Call its method Scan with the Bitmap object containing the barcode image; it returns a string [] value where the scanning result is stored. The class BarcodeScanner to scan barcode images in its code. It can store and add enterprise-level barcodes in VB.NET and C#.
Here is the code:
private void btnScan_Click(object sender, EventArgs e)
{
//scan the barcode
string [] datas = Spire.Barcode.BarcodeScanner.Scan("barcode.png");
//show the scan result
this.TextB_ScanResult.Text = datas [0];
}
private void btnScan_Click(object sender, EventArgs e)
{
//scan the barcode
string [] datas = Spire.Barcode.BarcodeScanner.Scan("barcode.png");
//show the scan result
this.TextB_ScanResult.Text = datas [0];
}
Private Sub btnScan_Click(ByVal sender As Object, ByVal e As EventArgs)
'scan the barcode
Dim datas() As String = Spire.Barcode.BarcodeScanner.Scan("barcode.png")
'show the scan result
Me.TextB_ScanResult.Text = datas (0)
End Sub

IronBarcode is used to generate enterprise-level barcode formats of barcode images. It also enables developers to rotate barcode images, as well as create barcode image borders to assist further in formatting barcode images. IronBarcode provides reliable barcode generation when compared to other generators, and it generates high-quality barcode images. In short, we can get our desired output image format with IronBarcode. The barcode images that are generated by IronBarcode are best due to we may create, style, and export a barcode with a single line of code. barcode developers easy integration with other net applications and provide the different barcode types it can recognize barcode and postal barcodes easily. The component model of the library is also more efficient — each component mode enables developers to generate barcodes with different styles and different formats. The code is very simple and it's just one line. The recognition component and recognition functionality are better in IronBarcode. The API mode makes it more reliable than the other generators.
Spire.Barcode for .NET provides a way to integrate barcode processing. With just one line of code we can create barcodes and read 1D & 2D barcodes. Spire.BarCode supports variable common image formats, such as Bitmap, JPG, PNG, EMF, TIFF, GIF, and WMF. We can therefore create barcode images, and barcode image developers can easily add barcode generation and make barcodes with just a few lines of code.
IronBarcode packages provide better licenses and support compared to Spire.Barcode, and Spire is more expensive. IronBarcode starts from $749 while Spire.Barcode starts from $898, so IronBarcode is clearly more cost-effective than Spire. IronBarcode also provides more features than Spire.Barcode. It also provides better support and a money-back guarantee, which Spire does not. IronBarcode offers long-term support and is easily integrated with API mode .NET applications. It is easy to integrate with a new document (C, VB.NET and C#), and it also generates multiple barcodes of code.
