How to Generate QR Code in C#

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.

 

private void Form1_Load(object sender, EventArgse)
{
   Bitmap img = GenerateQR(50, 50, "Becauset he DataContext class is the entry point to the LINQ-to-SQL data model");
   img.Save(@"D:\TESTING FROM APPS c#/hari.bmp");// Give the path to save the generated bitmap image
}
public Bitmap GenerateQR(int width, int height, stringtext)
{
   var bw = new ZXing.BarcodeWriter();
   var encOptions = new Xing.Common.EncodingOptions() { Width= width, Height = height, Margin = 0 };
   bw.Options= encOptions;
   bw.Format =ZXing.BarcodeFormat.QR_CODE;
   var result = new Bitmap(bw.Write(text));

   return result;
}
