get_RectMicroQRVersion()	Version of recognized RectMicroQR Code. From R7x43 to R17x139.
GetHashCode() const override	Returns the hash code for this instance.
ToString() const override	Returns a human-readable string representation of this QRExtendedParameters.

Remarks

This sample shows how to get QR Structured Append data

[C#]
using (BarCodeReader reader = new BarCodeReader(@"c:\test.png", DecodeType.QR))
{
    foreach (BarCodeResult result in reader.ReadBarCodes())
    {
        Console.WriteLine("BarCode Type: " + result.CodeTypeName);
        Console.WriteLine("BarCode CodeText: " + result.CodeText);
        Console.WriteLine("QR Structured Append Quantity: " + result.Extended.QR.QRStructuredAppendModeBarCodesQuantity);
        Console.WriteLine("QR Structured Append Index: " + result.Extended.QR.QRStructuredAppendModeBarCodeIndex);
        Console.WriteLine("QR Structured Append ParityData: " + result.Extended.QR.QRStructuredAppendModeParityData);
    }
}
[VB.NET]
Using reader As New BarCodeReader("c:\test.png", DecodeType.QR)
    For Each result As BarCodeResult In reader.ReadBarCodes()
        Console.WriteLine("BarCode Type: " + result.CodeTypeName)
        Console.WriteLine("BarCode CodeText: " + result.CodeText)
        Console.WriteLine("QR Structured Append Quantity: " + result.Extended.QR.QRStructuredAppendModeBarCodesQuantity)
        Console.WriteLine("QR Structured Append Index: " + result.Extended.QR.QRStructuredAppendModeBarCodeIndex)
        Console.WriteLine("QR Structured Append ParityData: " + result.Extended.QR.QRStructuredAppendModeParityData)
    Next
End Using
