I'm glad to tell you that pqScan .NET Barcode Scanner is able to scan multiple barcodes from a picture in once. There are two scenarios in the return barcode results.
First is that there are two or more different type of barcodes in the image, such as one Code 128, one QR Code, and one Data Matrix. While you scanning this barcode picture, you can get all the three barcode results. Second is that there are multiple barcodes with equal barcode symbol in one image, our .net barcode reader control can also decode all this barcode type out to you.
Before you using our barcode reader toolkit, make sure your projects is running in the .net framework 2.0 or highter. The C# example code is only one line, it's really simple and easy to use.
static void Main(string args)
//load barcode picture to memory
Bitmap bmp = Bitmap.FromFile("barcode-image.png");
//scan all PDF 417 barcde in this image.
BarcodeResult results = BarCodeScanner.Scan(bmp, BarCodeType.PDF417);
foreach (BarcodeResult result in results)
//show each PDF 417 message
Console.WriteLine("PDF-417 Barcode data : ");
Hope the C# code can be helpful.
