以下是調用：

         {
              // 在這裡放置使用者程式碼以初始化網頁
              this.txt_UserID.Text=this.GetCookieValue("UserName","UserID");//取得用戶名
         }

         private void btn_Submit_Click(object sender, System.EventArgs e)
         {
#region用Cookie進行保存登入用戶名
              if(this.chb_IsSave.Checked)
              {
                   //將用戶保存一個小時，具體設置可以進行調整。。
                   //這裡用了固定的公用的cookie用戶UserName,用戶編號UserID進行訪問
                   CreateCookieValue("UserName","UserName","UserID",this.txt_UserID.Text,DateTime.Now+new TimeSpan(0,1,0,0));//設置保存用戶名
              }
