    //我页面上有两个Panel,分别用来做两部分文件的上传
     //如果使用HttpFileCollection  Request.Files的方法,获取的是页面上所有上传控件的值.
    //因为我是动态添加的控件
    //控件的id分别是mypic1,mypic2.....myfile1,myfile2....
    //小弟不才,想请教各位关于怎样只获取一个panel里面的上传控件的值?

protected void AddPic_Click(object sender, EventArgs e)
    {
            HttpFileCollection hfc = Request.Files;
            string f_Name, f_Size, f_Type, f_Extented, newFileName, f_Path;
            for (int i = 0; i <= hfc.Count - 1; i++)
            {
                HttpPostedFile hpf = hfc[i];
                if (hpf.FileName != "")
                {
                    f_Name = Path.GetFileName(hpf.FileName);
                    Response.Write(i+"、"+f_Name+"<br>");
                 }
      }
