You can use LEADTOOLS Barcode SDK technology in your application.
https://www.leadtools.com/sdk/barcode
For your use-case you can leverage the BarcodeWriter class to generate a barcode with the desired encoded data.

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);
}

Hi,

You can search and install Free Spire.Barcode library via NuGet to generate barcode image and scan barcode image, it's quite easy.

The following example shows how to generate QR code (it also supports lots of other barcode types):

The following example shows how to scan barcode image:
