You can use LEADTOOLS Barcode Pro SDK technology in your application.
https://www.leadtools.com/sdk/barcode
The Barcode Pro SDK allows you to not only read barcodes but also write supported barcodes to an image or document.
Here is some sample code:
using (RasterCodecs _codecs = new RasterCodecs())
using (RasterImage _image = _codecs.Load(fileName, 1))
{
    BarcodeEngine bcEngine = new BarcodeEngine();
    // Read Barcode
    BarcodeData data = bcEngine.Reader.ReadBarcode(barcodeImage, LeadRect.Empty, BarcodeSymbology.Unknown);
    if (data != null)
    {
        Console.WriteLine("Barcode Found");
        Console.WriteLine($"Value: {data.Value}\n" +
                    $"Symbology: {data.Symbology}\n" +
                    $"Bounds: {data.Bounds}");
        Console.WriteLine("=====================================");
    }
    // Write Barcode
    BarcodeEngine engine = new BarcodeEngine();
    // Use can use the writer now, for example, write a UPCA barcode to an image:
    BarcodeData data = new BarcodeData(BarcodeSymbology.UPCA, "01234567890");
    data.Bounds = new LeadRect(0, 0, 400, 200);
    engine.Writer.WriteBarcode(_image, data, null);
}
