Need help to read Barcode value

Yapa Appuhamy

Hi,

I have a requirement to read a Barcode & get the value to a textbox on my Web Form. It needs to read the Barcode from a Camera (Back Camera of a Phone). So, can anyone help me to develop the System with relevant guidance?

Regards

MV.

Once you obtain the images form the camera, you can use LEADTOOLS to recognize barcodes.
The barcode reading code is simple and similar to this:
BarcodeEngine engine = new BarcodeEngine();
BarcodeReader reader = engine.Reader;
BarcodeData[] barcode = reader.ReadBarcodes(image, LeadRect.Empty, 0, null);
if (barcode != null)
Console.WriteLine("Data:{0}, Found at location {1}", barcode[0].Value, barcode[0].Bounds);
After reading the barcode, you can set it to your textbox.

You can find more details in the following link:

Also, you can use the cloud services for reading barcodes, see this link:

Capture the barcode image from the camera, and use a 3rd party barcode library like Free Spire.Barcode for .NET to detect the barcode data from the image.
