C#產生二維碼（ThoughtWorks.QRCode）

標籤：

本人使用的是ThoughtWorks.QRCode.dll,在網上可以下載，但要注意dll檔案的完整性和準確性，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檔案代碼：

 1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Web; 5 using System.Web.UI; 6 using System.Web.UI.WebControls; 7 using ThoughtWorks.QRCode; 8 using ThoughtWorks.QRCode.Codec; 9 using System.Drawing;10 using System.Text;11 12 namespace 二維碼產生.Pages13 {14     public partial class CreateErWeiMa : System.Web.UI.Page15     {16         protected void Page_Load(object sender, EventArgs e)17         {18 19         }20 21         protected void Button1_Click(object sender, EventArgs e)22         {23             ThoughtWorksQRCode(this.TextBox1.Text);24 25         }26 27         private void ThoughtWorksQRCode(string strtxt)28         {29             try30             {31                 Bitmap bt;32                 string enCodeString = strtxt;33                 QRCodeEncoder qrCodeEncoder = new QRCodeEncoder();34                 bt = qrCodeEncoder.Encode(enCodeString, Encoding.UTF8);35                 string filename = DateTime.Now.ToString("yyyymmddhhmmss");37                 filename = filename.Replace(" ", "");38                 filename = filename.Replace(":", "");39                 filename = filename.Replace("-", "");40                 filename = filename.Replace(".", "");41                 bt.Save(Server.MapPath("~/image/") + filename + ".jpg");42                 this.Image1.ImageUrl = "~/image/" + filename + ".jpg";43             }44             catch (Exception e)45             {46                 throw e;47             }48            49         }50 51     }52 }
