ASP.Net實現圖片上傳：

實現圖片上傳的方法

 1 try
 2         {
 3             //((Image)gvGradeUser.FindControl(ImageGrade)).ImageUrl.ToString().Trim();
 4             //根據等級的編修改
 5              int enbale = 0;
 6             if (ddlStart.Text.ToString().Trim() == "正常")
 7             {
 8                 enbale = 0;

13             }
14             //圖片存在時
