            context.Request.ContentEncoding = Encoding.GetEncoding("gb2312");
            context.Response.ContentType = "text/plain";
                       if (context.Request.Form["_type"] != null)
            {
                switch (context.Request.Form["_type"])
                {
                    case "_AllPageNum": SendAllPageNum(context); break;
                                      default: break;
                }
            }
        }
   private void SendAllPageNum(HttpContext context)
        {
            string TableName = context.Request.Form["_TableName"];
            string SelectWhere = context.Request.Form["_SelectWhere"];                 }string SelectWhere = context.Request.Form["_SelectWhere"] 页面输入的是汉字，但是传过来
