BarCode Generator

One way to generate barcodes in ASP.NET project is to use the LEADTOOLS barcode engine. The server-side C# code will look like this:

RasterImage bitmapImage = RasterImage.Create(400, 150, 24, 300, RasterColor.White);
BarcodeWriteOptions writeOptions = _barcodeEngine.Writer.GetDefaultOptions(BarcodeSymbology.Code3Of9);
string sampleData = "123-45678";
// There are many supported types, not just Code39
_barcodeEngine.Writer.WriteBarcode(bitmapImage, new BarcodeData(BarcodeSymbology.Code3Of9, sampleData), writeOptions);
// Save the image as PNG to a stream
RasterCodecs codecs = new RasterCodecs();
MemoryStream ms = new MemoryStream();
codecs.Save(bitmapImage, ms, RasterImageFormat.Png, 24);
//you can then store the memory stream anywhere

If you would like to try it, you can get a free evaluation edition of the library from this page: https://www.leadtools.com/downloads?category=main.
The evaluation is fully-functional (but time-limited) and comes with free technical support through email and chat.
