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;
            }
           
        }

    }
}
