在userHandler.ashx页面，怎么接收页面上的传图控件。

<input class="mini-htmlfile" name="User_Face" limitType="*.jpg;*.png;*.gif;*.jpeg" />
function SaveData() {
      var o = form.getData();

      form.validate();
      if (form.isValid() == false) return;

      var json = mini.encode([o]);
      $.ajax({
         url: "../ybt_inc/ajax/userHandler.ashx?method=SaveUser",
         type: 'post',
         data: { data: json },
         cache: false,
         success: function (text) {
            if (text == "ok")
            {
                  alert("增加成功！");
            }
            else if (text == "ExitUser") {
                  alert("该手机号已存在，请重新添加！");
            }
            else {
                  alert("添加失败：" + text);
            }
            //CloseWindow("save");
         },
         error: function (jqXHR, textStatus, errorThrown) {
            alert(jqXHR.responseText);
            CloseWindow();
         }
      });
}
userHandler.ashx
      public void ProcessRequest(HttpContext context)
      {
         Eble_UserService userService = new Eble_UserService();
         switch (context.Request["method"])
         {
            case "SaveUser":
                  String json = context.Request["data"];
                  ArrayList rows = (ArrayList)Test.JSON.Decode(json);
                  foreach (Hashtable row in rows)
                  {
                     String id = row["id"] != null ? row["id"].ToString() : "";
                     //根据记录状态，进行不同的增加、删除、修改操作
                     String state = row["_state"] != null ? row["_state"].ToString() : "";

                     if (state == "added" || id == "")          //新增：id为空，或_state为added
                     {
                                  int tag = userService.AddFast(Save(row));
                                 if (tag > 0) { context.Response.Write("ok"); }
                     }
                     else if (state == "removed" || state == "deleted")
                     {
                        // new Test.TestDB().DeleteEmployee(id);
                     }
                     else if (state == "modified" || state == "") //更新：_state为空或modified
                     {
                        //new Test.TestDB().UpdateEmployee(row);

                     }
                  }

                  break;
         }

      }
private Eble_User Save(Hashtable htuser)
         // 获得程序路径
         string tempFile = HttpContext.Current.Request.PhysicalApplicationPath;

         //找到目标文件对象
         HttpPostedFile uploadFile = HttpContext.Current.Request.Files[htuser["User_Face"].ToString()];

         // 如果有文件, 则保存到一个地址
         if (uploadFile != null)
         {
            uploadFile.SaveAs(string.Format("{0}{1}{2}", tempFile, "ybt_upload\\member\\member_Org\\", uploadFile.FileName));
            User_Face = uploadFile.FileName;
         }
         else { User_Face = null; }
return User_Face;
