How to create bar code using c#

You can use LEADTOOLS Barcode Pro SDK technology in your application.

https://www.leadtools.com/sdk/products/barcode-pro

You can leverage the BarcodeWriter class, which allows you to write any LEADTOOLS supported barcode type to an image.

I am unaware of what barcode type you are wanting to generate, so the sample code below will show how to write a QR barcode to an image.

// Write/Generate Barcode using LEADTOOLS SDK
using (RasterImage _image = RasterImage.Create(2550, 3300, 24, 300, RasterColor.White))
{
BarcodeEngine _engine = new BarcodeEngine();
BarcodeWriter _writer = _engine.Writer;
// Set barcode options
QRBarcodeData _qrData = BarcodeData.CreateDefaultBarcodeData(BarcodeSymbology.QR) as QRBarcodeData;
_qrData.SymbolModel = QRBarcodeSymbolModel.Model1AutoSize;
_qrData.Value = "QR Data 1";
_qrData.Bounds = new LeadRect(0, 0, _image.ImageWidth, _image.ImageHeight);
QRBarcodeWriteOptions _options = new QRBarcodeWriteOptions();
_options.GroupNumber = 0;
_options.GroupTotal = 0;
_options.HorizontalAlignment = BarcodeAlignment.Near;
_options.VerticalAlignment = BarcodeAlignment.Near;
_options.XModule = 30;
_options.ECCLevel = QRBarcodeECCLevel.LevelL;
// Write image to barcode
_writer.WriteBarcode(_image, _qrData, _options);
// Save image
using (RasterCodecs codecs = new RasterCodecs())
codecs.Save(_image, @"FILE PATH TO OUTPUT IMAGE", RasterImageFormat.Png, 0);
}
