''' <summary>
''' Verifies the barcode during the barcode recognition process.
''' </summary>
Private Shared Sub VerifyBarcodeMethod(reader As BarcodeReader, barcodeInfo As IBarcodeInfo)   
    If barcodeInfo.ReadingQuality < 0.2 Then   
        barcodeInfo.Confidence = 0   
    End If   
End Sub   
   
' ...
' reader.Settings.VerifyBarcodeMethod = VerifyBarcodeMethod;
' ...


/// <summary>
/// Verifies the barcode during the barcode recognition process.
/// </summary>
static void VerifyBarcodeMethod(BarcodeReader reader, IBarcodeInfo barcodeInfo)
{
    if (barcodeInfo.ReadingQuality < 0.2)
        barcodeInfo.Confidence = 0;
}

// ...
// reader.Settings.VerifyBarcodeMethod = VerifyBarcodeMethod;
// ...
