C#生成二維碼（ThoughtWorks.QRCode）

本人使用的是ThoughtWorks.QRCode.dll,在網上可以下載，但要注意dll文件的完整性和準確性，本人之前下載的dll就是不正確導致調試時出現錯誤。

以下為cs文件代碼：

 using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Web;
 using System.Web.UI;
 using System.Web.UI.WebControls;
 using ThoughtWorks.QRCode;
 using ThoughtWorks.QRCode.Codec;
 using System.Drawing;
 using System.Text;

 namespace 二維碼生成.Pages
 {
     public partial class CreateErWeiMa : System.Web.UI.Page
     {
         protected void Page_Load(object sender, EventArgs e)
         {

         }

         protected void Button1_Click(object sender, EventArgs e)
         {
             ThoughtWorksQRCode(this.TextBox1.Text);

         }

         private void ThoughtWorksQRCode(string strtxt)
         {
             try
             {
                 Bitmap bt;
                 string enCodeString = strtxt;
                 QRCodeEncoder qrCodeEncoder = new QRCodeEncoder();
                 bt = qrCodeEncoder.Encode(enCodeString, Encoding.UTF8);
                 string filename = DateTime.Now.ToString("yyyymmddhhmmss");
                 filename = filename.Replace(" ", "");
                 filename = filename.Replace(":", "");
                 filename = filename.Replace("-", "");
                 filename = filename.Replace(".", "");
                 bt.Save(Server.MapPath("~/image/") + filename + ".jpg");
                 this.Image1.ImageUrl = "~/image/" + filename + ".jpg";
             }
             catch (Exception e)
             {
                 throw e;
             }

         }

     }
 }
