        if (fileExt == ".jpg" || fileExt == ".gif")  
 
        {  
 
            try 
 
            {  
 
                FileUpload1.SaveAs(Server.MapPath("upload") + "\\" + FileUpload1.FileName);  
 
                Label1.Text = "客户端路径：" + FileUpload1.PostedFile.FileName + "
" +  
 
                              "文件名：" + System.IO.Path.GetFileName(FileUpload1.FileName) + "

            }  
 
            catch (Exception ex)  
 
            {  
 
                Label1.Text = "发生错误：" + ex.Message.ToString();  
 
            }
