需要用到下面两个函数,具体是哪位大侠先写的就不知道了。先谢谢。

        /// <summary>        /// 用来给ASHX传递的参数进行编码         /// </summary>        /// <param name="str"></param>        /// <returns></returns>        public static string Escape(string str)        {            StringBuilder sb = new StringBuilder();            foreach (char c in str)            {                sb.Append((Char.IsLetterOrDigit(c)                    || c == '-' || c == '_' || c == '\\'                    || c == '/' || c == '.') ? c.ToString() : Uri.HexEscape(c));            }            return sb.ToString();        }

        /// <summary>        /// 用来解码Escape编码后的内容         /// </summary>        /// <param name="str"></param>        /// <returns></returns>        public static string UnEscape(string str)        {            StringBuilder sb = new StringBuilder();            int len = str.Length;            int i = 0;            while (i != len)            {                if (Uri.IsHexEncoding(str, i))                    sb.Append(Uri.HexUnescape(str, ref i));                else                    sb.Append(str[i++]);            }            return sb.ToString();        }

在ASPX页面的.cs文件里

        protected void Page_Load(object sender, EventArgs e)        {           ddlyxlx.Items.FindByValue(Request["Ddh"] == null ? "0" : CommandInfo.UnEscape(Server.UrlDecode(Request["Ddh"].ToString()))).Selected = true;        }        protected void btn_Search_Click(object sender, EventArgs e)        {            string _Url = string.Format("Check_TableDestineYanXi.aspx?StartDate={0}&EndDate={1}&CurrentDateNav={2}&Ddh={3}", txtStartDate.Text, txtEndDate.Text, DateNavSelect1.GetCurrentDateNav, CommandInfo.Escape(Server.UrlEncode(ddlyxlx.SelectedValue)));            Response.Redirect(GetUrl());        }

Ashx文件里面接收方法

string Ddh = (context.Request["Ddh"] == null ? "" : System.Web.HttpContext.Current.Server.UrlDecode(CommandInfo.UnEscape(context.Request["Ddh"])));

即可接收到中文的参数，不用修改web.config文件。
