通过HTTP80端口发送手机短信

由于联系的手机厂商为只能提供从HTTP80端口发送信息，故对此编写了以下代码：

　　　　string MobileNo = "";//手机号码
           string MsgContent = "";//短信内容
                WebProxy myproxy = new WebProxy("172.22.252.66:80", true);
                myproxy.Credentials = new NetworkCredential("Yong-Chao_Lu", "!lyc760408", "maintek");

                string[] MobileCode = MobileNo.Split(';');

                foreach (string curCode in MobileCode)
                {

                    if (curCode.Trim().Length > 8)//号码长度判断
                    {
                        WebRequest WReq;
                        WebResponse WResp;
                        string url = "http://221.224.134.226/guanshuo/insert.asp?tel_no=" + curCode + "&content=" + MsgContent + "&user_name=客户名称&user_IP=客户标识";
                        WReq = WebRequest.Create(url);
                        WReq.Proxy = myproxy;
                        WResp = WReq.GetResponse();
                    }
                }
