Generate QR Code in C#

  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.

  3. I have attached the dll for you to download.

  4. We can also generate other codes such as MAXICODE,UCP and so on.

  1. private void Form1_Load(object sender, EventArgse)
  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
  5. }
  6. public Bitmap GenerateQR(int width, int height, stringtext)
  7. {
  8. var bw = new ZXing.BarcodeWriter();
  9. var encOptions = new Xing.Common.EncodingOptions() { Width= width, Height = height, Margin = 0 };
  10. bw.Options= encOptions;
  11. bw.Format =ZXing.BarcodeFormat.QR_CODE;
  12. var result = new Bitmap(bw.Write(text));
  14. return result;
  15. }
