  1. I am using a third party dll named as Zxing. It’s Originally developed in java platform.

  2. We can specify the Height and Width of generated QR image.

  2. {  
  3.    Bitmap img = GenerateQR(50, 50, "Becauset he DataContext class is the entry point to the LINQ-to-SQL data model");  
  4.    img.Save(@"D:\TESTING FROM APPS c#/hari.bmp");// Give the path to save the generated bitmap image
