Usually QRCode return a string value.
Now, if you have string value you can use it whatever or wherever you need.

In this case, the Barcode Reader for .NET is highly recommended.

Here is a sample code of C# to read qr code :

using BusinessRefinery.Barcode;
using BusinessRefinery.Barcodes.Reader;

BusinessRefinery.Barcode.QRCode barcode = new QRCode();
barcode.Code = "QRCodeReader123";
barcode.Version = QRCodeVersion.V3;
barcode.Rotate = Rotate.Rotate180;

Bitmap bmp = barcode.drawBarcodeOnBitmap();

string[] barcodes = BarCodeReader.scanBarCode(bmp,
BusinessRefinery.Barcodes.Reader.BarCodeType.QRCODE);

Hope it helps!
