Which C# Barcode Library Should You Use for .NET Development?

What Makes IronBarcode the Best Overall Choice?

IronBarcode from Iron Software delivers complete barcode functionality for .NET developers. The library supports over 50 barcode types, including both linear barcodes (UPC, EAN, Code128) and 2D formats like QR codes, Data Matrix, and PDF417. Unlike single-purpose libraries, IronBarcode excels at both barcode generation and recognition.

The implementation handles real-world scanning challenges exceptionally well. Production scenarios with damaged or poorly printed barcodes achieve 98%+ success rates through image preprocessing filters. The library automatically applies sharpening and contrast adjustments to improve readability and manages orientation issues with its AutoRotate feature. Your high-speed warehouse applications processing 1000+ barcodes per minute can use reading speed options to balance accuracy with performance.

// Configure for high-speed scanning with image correction
using IronBarCode;

var barcodeReaderOptions = new BarcodeReaderOptions
{
    Speed = ReadingSpeed.Faster,
    ExpectMultipleBarcodes = true,
    AutoRotate = true,
    ImageFilters = new[] { 
        ImageFilterType.SharpenFilter,
        ImageFilterType.ContrastFilter
    }
};

// Read from damaged barcode image
var results = BarcodeReader.Read("warehouse-scan.jpg", barcodeReaderOptions);
foreach (var barcode in results)
{
    Console.WriteLine($"Type: {barcode.BarcodeType}, Value: {barcode.Value}");
}

// Configure for high-speed scanning with image correction
using IronBarCode;

var barcodeReaderOptions = new BarcodeReaderOptions
{
    Speed = ReadingSpeed.Faster,
    ExpectMultipleBarcodes = true,
    AutoRotate = true,
    ImageFilters = new[] { 
        ImageFilterType.SharpenFilter,
        ImageFilterType.ContrastFilter
    }
};

// Read from damaged barcode image
var results = BarcodeReader.Read("warehouse-scan.jpg", barcodeReaderOptions);
foreach (var barcode in results)
{
    Console.WriteLine($"Type: {barcode.BarcodeType}, Value: {barcode.Value}");
}

The library's fault tolerance capabilities ensure reliable reading under challenging conditions. When processing multi-page TIFF or GIF files, IronBarcode automatically handles all frames without manual separation. Enterprise deployments benefit from complete security measures including DigiCert certification and tamper protection.

The library works directly with PDF documents, enabling you to write barcodes or detect them within existing files. IronBarcode's reading engine automatically handles imperfect scans by applying corrections like rotation, deskewing, and enhancement. This approach provides fast, accurate scanning in real-world conditions. You can generate barcode images in multiple formats or insert them into HTML documents and multi-page PDFs.

For generation capabilities, IronBarcode provides extensive customization. You can style barcodes with custom colors, set margins, and add logos to QR codes. The library supports Unicode encoding for international characters. Your application can save barcodes in various formats or export as streams for web APIs and cloud services. When creating barcodes from data sources, the library manages text, URLs, IDs, and binary data seamlessly.

// Generate customized QR code with logo
var qrCode = QRCodeWriter.CreateQrCodeWithLogo("___PROTECTED_URL_176___", "logo.png", 300);
qrCode.ChangeBarCodeColor(System.Drawing.Color.Navy)
      .SetMargins(10)
      .SaveAsImage("branded-qr.png");

// Create styled barcode with annotations
var styledBarcode = BarcodeWriter.CreateBarcode("PRODUCT-12345", BarcodeWriterEncoding.Code128);
styledBarcode.ResizeTo(400, 150)
             .SetMargins(20)
             .ChangeBarCodeColor(Color.DarkBlue)
             .AddAnnotationTextAboveBarcode("Product SKU")
             .SaveAsImage("styled-product-barcode.png");

// Generate customized QR code with logo
var qrCode = QRCodeWriter.CreateQrCodeWithLogo("___PROTECTED_URL_176___", "logo.png", 300);
qrCode.ChangeBarCodeColor(System.Drawing.Color.Navy)
      .SetMargins(10)
      .SaveAsImage("branded-qr.png");

// Create styled barcode with annotations
var styledBarcode = BarcodeWriter.CreateBarcode("PRODUCT-12345", BarcodeWriterEncoding.Code128);
styledBarcode.ResizeTo(400, 150)
             .SetMargins(20)
             .ChangeBarCodeColor(Color.DarkBlue)
             .AddAnnotationTextAboveBarcode("Product SKU")
             .SaveAsImage("styled-product-barcode.png");

IronBarcode ensures cross-platform compatibility with .NET Framework, .NET Core, .NET Standard, and .NET MAUI. Your Visual Studio projects work across web, desktop, cloud, or mobile platforms. The library supports deployment on Linux, macOS, Docker containers, Azure, and AWS Lambda. Installation through the NuGet package manager is straightforward, and the official API reference includes clear code examples for implementing QR code generation, QR code writing, and scanning.

When working with System.Drawing objects, IronBarcode provides cross-platform compatibility through IronDrawing. The output data formats include complete metadata about detected barcodes, including coordinates, dimensions, and confidence scores. High-performance scenarios benefit from async and multithreaded operations to process thousands of barcodes concurrently.

Why Choose ZXing.Net for Open-Source Projects?

ZXing.Net provides a .NET port of the Zebra Crossing (ZXing) open-source library. This free solution supports common barcode formats like QR codes, UPC-A, and Code128. For smaller projects needing basic barcode creation or reading, ZXing.Net offers a lightweight option. The barcode quickstart guide demonstrates how modern libraries simplify these tasks.

The library's format support remains limited compared to commercial alternatives. It handles standard 1D formats and popular 2D codes but lacks newer formats like GS1 DataBar or specialized industrial codes. Performance benchmarks show ZXing.Net processes 100-200 barcodes per minute, which may be insufficient for high-volume applications requiring improve reading speeds. Consider libraries with configurable speed options that balance accuracy and throughput.

// Basic ZXing.Net barcode reading
using ZXing;

var reader = new BarcodeReader();
var result = reader.Decode(new Bitmap("barcode.png"));
if (result != null)
{
    Console.WriteLine($"Decoded: {result.Text}");
}

// ZXing.Net QR code generation
var writer = new BarcodeWriter
{
    Format = BarcodeFormat.QR_CODE,
    Options = new QrCodeEncodingOptions
    {
        Width = 300,
        Height = 300,
        Margin = 2
    }
};
var bitmap = writer.Write("___PROTECTED_URL_177___");
bitmap.Save("qr-code.png");

// Basic ZXing.Net barcode reading
using ZXing;

var reader = new BarcodeReader();
var result = reader.Decode(new Bitmap("barcode.png"));
if (result != null)
{
    Console.WriteLine($"Decoded: {result.Text}");
}

// ZXing.Net QR code generation
var writer = new BarcodeWriter
{
    Format = BarcodeFormat.QR_CODE,
    Options = new QrCodeEncodingOptions
    {
        Width = 300,
        Height = 300,
        Margin = 2
    }
};
var bitmap = writer.Write("___PROTECTED_URL_177___");
bitmap.Save("qr-code.png");

However, it lacks modern functionality. The barcode writing API remains basic, and the library doesn't provide automatic handling of encoding errors or image correction. You may face accuracy issues with imperfect scans, rotated codes, or poor lighting conditions. Testing with damaged barcodes shows 60-70% success rates without manual preprocessing. For better results, consider libraries with built-in image filters and automatic rotation capabilities. The lack of error correction configuration limits effectiveness in challenging scenarios.

When Should You Use Aspose.BarCode?

Aspose.BarCode for .NET targets enterprise use cases with both generation and recognition capabilities. It supports most barcode types and integrates with the Aspose suite for embedding barcodes in Word, Excel, or PDF documents. For similar functionality, IronBarcode's PDF integration offers simpler APIs. The library can stamp barcodes on PDFs with precise positioning.

The library offers complete format support including postal barcodes and specialized 2D codes. Generation quality excels with precise control over module size, quiet zones, and error correction levels. However, the API follows Aspose's unique conventions which may feel unfamiliar. For comparison, IronBarcode's styling approach uses more intuitive method names. The custom QR code example demonstrates cleaner API design.

// Aspose.BarCode generation with custom settings
using Aspose.BarCode.Generation;

var generator = new BarcodeGenerator(EncodeTypes.DataMatrix, "ASPOSE-123");
generator.Parameters.Barcode.XDimension.Millimeters = 0.5f;
generator.Parameters.Barcode.DataMatrix.DataMatrixEcc = DataMatrixEccType.Ecc200;
generator.Save("datamatrix.png", BarCodeImageFormat.Png);

// Reading barcodes with specific settings
var reader = new BarCodeReader("barcode.png", DecodeType.AllSupportedTypes);
reader.QualitySettings = QualitySettings.HighPerformance;
foreach (BarCodeResult result in reader.ReadBarCodes())
{
    Console.WriteLine($"Type: {result.CodeTypeName}, Value: {result.CodeText}");
}

// Aspose.BarCode generation with custom settings
using Aspose.BarCode.Generation;

var generator = new BarcodeGenerator(EncodeTypes.DataMatrix, "ASPOSE-123");
generator.Parameters.Barcode.XDimension.Millimeters = 0.5f;
generator.Parameters.Barcode.DataMatrix.DataMatrixEcc = DataMatrixEccType.Ecc200;
generator.Save("datamatrix.png", BarCodeImageFormat.Png);

// Reading barcodes with specific settings
var reader = new BarCodeReader("barcode.png", DecodeType.AllSupportedTypes);
reader.QualitySettings = QualitySettings.HighPerformance;
foreach (BarCodeResult result in reader.ReadBarCodes())
{
    Console.WriteLine($"Type: {result.CodeTypeName}, Value: {result.CodeText}");
}

Large organizations appreciate Aspose's barcode API and standards support. However, it has a steeper learning curve and higher cost. Performance testing shows 500-800 barcodes per minute with 85-90% accuracy on damaged codes. Libraries with advanced reader settings achieve similar results with easier configuration. When processing streams, both libraries provide efficient memory-based processing. For MSI barcode recognition, proper configuration remains essential.

Is BarcodeLib Right for Simple Generation Tasks?

Unlike complete solutions, BarcodeLib only generates barcodes without scanning capabilities. BarcodeLib excels at simple barcode creation for common formats like Code39, Code128, or UPC. For both generation and reading capabilities, consider complete solutions. The barcode generation features in modern libraries offer greater flexibility.

BarcodeLib handles basic generation tasks with a straightforward API. Your application can produce barcodes as images with customizable size, colors, and text annotations. The library generates industry-compliant barcodes for retail and logistics. However, customization remains limited — you cannot add logos or apply advanced styling like gradient fills or custom margins. Modern libraries offer complete styling including colors, resizing, and annotations.

// Simple barcode generation with BarcodeLib
using BarcodeLib;

var barcode = new Barcode();
barcode.IncludeLabel = true;
barcode.AlternateLabel = "Product Code";
barcode.RotateFlipType = RotateFlipType.RotateNoneFlipNone;
var img = barcode.Encode(TYPE.CODE128, "12345678", Color.Black, Color.White, 300, 150);
img.Save("simple-barcode.png", ImageFormat.Png);

// Limited customization options
barcode.LabelPosition = LabelPositions.BOTTOMCENTER;
barcode.EncodedType = TYPE.UPCA;
var upcImage = barcode.Encode("123456789012");

// Simple barcode generation with BarcodeLib
using BarcodeLib;

var barcode = new Barcode();
barcode.IncludeLabel = true;
barcode.AlternateLabel = "Product Code";
barcode.RotateFlipType = RotateFlipType.RotateNoneFlipNone;
var img = barcode.Encode(TYPE.CODE128, "12345678", Color.Black, Color.White, 300, 150);
img.Save("simple-barcode.png", ImageFormat.Png);

// Limited customization options
barcode.LabelPosition = LabelPositions.BOTTOMCENTER;
barcode.EncodedType = TYPE.UPCA;
var upcImage = barcode.Encode("123456789012");

BarcodeLib remains solid for quick, free solutions without larger SDK overhead. However, it doesn't support advanced use cases like PDFs, mobile apps, or scanning. The library lacks newer formats and Unicode encoding. For 1BPP barcode images or streaming barcodes, you'll need reliable solutions. When using MSI installers, beware of potential missing DLL issues.

Why Consider Dynamsoft for High-Performance Scanning?
