Create Barcode

VB C#

using IronBarCode;
using System.IO;

// Create a barcode with one line of code
var myBarcode = BarcodeWriter.CreateBarcode("12345", BarcodeWriterEncoding.EAN8);

// Save the barcode as an image
myBarcode.SaveAsImage("EAN8.jpeg");

// A barcode can also be made from binary data (byte or stream)
string payloadAsString = "This is some random string";

byte[] payloadAsByteArray = System.Text.Encoding.Default.GetBytes(payloadAsString); // Byte array
var AztecBarcode = BarcodeWriter.CreateBarcode(payloadAsByteArray, BarcodeWriterEncoding.Aztec, 400, 400); // Create from Byte array

MemoryStream payloadAsStream = new MemoryStream(payloadAsByteArray); // MemoryStream
var AztecBarcode2 = BarcodeWriter.CreateBarcode(payloadAsStream, BarcodeWriterEncoding.Aztec, 400, 400); // Create from memory stream

Create Barcode

IronBarcode offers many options and customization when it comes to generating barcodes. Whether you’re developing a standalone barcode generator to produce images with standard encoding formats like EAN8, Code128, and Code39, or need a flexible library to integrate barcode creation into your existing application using ByteArray or MemoryStream, IronBarcode offers an easy-to-use solution with extensive features, including exporting to standard image formats like png, jpg, and jpeg.

Barcode Generator in C#

var myBarcode = BarcodeWriter.CreateBarcode("12345", BarcodeWriterEncoding.EAN8)

myBarcode.SaveAsImage("EAN8.jpeg")

BarcodeWriter.CreateBarcode("12345", BarcodeWriterEncoding.EAN8).ResizeTo(400, 100).SaveAsImage("EAN8.jpeg")

var AztecBarcode = BarcodeWriter.CreateBarcode(payloadAsByteArray, BarcodeWriterEncoding.Aztec, 400, 400)

var AztecBarcode2 = BarcodeWriter.CreateBarcode(payloadAsStream, BarcodeWriterEncoding.Aztec, 400, 400)

BarcodeWriter.CreateBarcode

After instantiating the BarcodeWriter class, we use BarcodeWriter.CreateBarcode to create a barcode. The method takes two required parameters: a string value and the BarcodeWriterEncoding enum that the developer chooses. We then save the barcode as an image for further use.

Other than creating a barcode, IronBarcode also allows developers to chain methods together for easier usage, as shown in line 3. It creates a barcode, then calls ResizeTo to resize the image given the height and width in pixels, ultimately saving the barcode as an image with SaveAsImage.

Furthermore, there are multiple variations of the BarcodeWriter.CreateBarcode method to cater to different situations and scenarios. If you need to create a barcode based on ByteArray, we can use another variation of the same CreateBarcode method, pass in ByteArray as the value, and specify the height and width of the barcode beforehand as well.

Similarly, if you need to create a barcode with a MemoryStream type variable, IronBarcode offers that as well; pass the MemoryStream variable as the first parameter in BarcodeWriter.CreateBarcode similarly to how it is done above and repeat the steps.

IronBarcode has all the options and scenarios prepared for developers looking to create simple barcode values, integrate them into their applications, and more!
