Class BarCodeReader

Class BarCodeReader

Namespace: Aspose.BarCode.BarCodeRecognition

Detta exempel visar hur man upptäcker Code39 och Code128 streckkoder.

using (BarCodeReader reader = new BarCodeReader())
{
    reader.SetBarCodeReadType(new MultyDecodeType(DecodeType.Code39, DecodeType.Code128));
    reader.SetBarCodeImage(@"c:\test.png");
    foreach (BarCodeResult result in reader.ReadBarCodes())
    {
        Console.WriteLine("BarCode Type: " + result.CodeTypeName);
        Console.WriteLine("BarCode CodeText: " + result.CodeText);
    }
}
Using reader As New BarCodeReader()
    reader.SetBarCodeReadType(New MultyDecodeType(DecodeType.Code39, DecodeType.Code128))
    reader.SetBarCodeImage("c:\test.png")
    For Each result As BarCodeResult In reader.ReadBarCodes()
        Console.WriteLine("BarCode Type: " + result.CodeTypeName)
        Console.WriteLine("BarCode CodeText: " + result.CodeText)
    Next
End Using
