You can install Free Spire.Barcode API(https://www.e-iceblue.com/Introduce/barcode-for-net-introduce.html), and add the below code to generate code 39 image easily. BarcodeSettings bs = new BarcodeSettings(); bs.Type = BarCodeType.Code39; bs.Data = "*ABC 12345* " ; BarCodeGenerator bg = new BarCodeGenerator(bs); bg.GenerateImage().Save( "Code39Code.png" );

You can use the LEADTOOLS Barcode Pro SDK in your application https://www.leadtools.com/sdk/products/barcode-pro You can utilize the BarcodeWriter class to write information to a code 3of9 barcode and add that barcode to an image. Here is some sample code: using (RasterCodecs _codecs = new RasterCodecs()) { using (RasterImage image = RasterImage.Create(2550, 3300, 24, 300, RasterColor.White)) { BarcodeEngine barcodeEngine = new BarcodeEngine(); BarcodeData data = new BarcodeData { Symbology = BarcodeSymbology.Code3Of9, Value = "CODE 3 OF 9" , Bounds = new LeadRect(10, 10, 600, 200) }; OneDBarcodeWriteOptions options = new OneDBarcodeWriteOptions { EnableErrorCheck = true , TextPosition = BarcodeOutputTextPosition.Default }; barcodeEngine.Writer.WriteBarcode(image, data, options); _codecs.Save(image, @ "C:\Temp\barcode.png" , RasterImageFormat.Png, 0); } }
