用“网建”平台发手机短信的C#代码

一直都用这个平台发手机短信的，今天做新项目的时候用到了，但是上来博客搜索不到，只好翻以前的源代码翻了好久才找到了，先记下来，以作备用：

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net;
using System.Text;
using System.Web;

namespace Niunan.CardShop.Web.Code
{
    public class SendMobile
    {

 /// 
返回发送短信的状态说明
 ///
 /// 
 /// 
 /// 
 public static string GetMobileMSMStatus(string str)
 {
     string s = "";
     switch (str)
     {
  case "-1":
      s = "没有该用户账户";
      break;
  case "-2":
      s = "密钥不正确（不是用户密码）";
      break;
  case "-3":
      s = "短信数量不足";
      break;
  case "-11":
      s = "该用户被禁用";
      break;
  case "-14":
      s = "短信内容出现非法字符";
      break;
  case "-4":
      s = "手机号格式不正确";
      break;
  case "-41":
      s = "手机号码为空";
      break;
  case "-42":
      s = "短信内容为空";
      break;
  default:
      s = "成功发送" + str + "条短信";
      break;
     }
     return s;
 }
 ///

 /// 
 /// 手机号码,多个手机号以,号相隔
 /// 短信内容
 public static string SendMobileMSM(string mobile, string body)
 {

     string url = "http://utf8.sms.webchinese.cn/?Uid=xxxxxx&Key=xxxxxx&smsMob=" + mobile + "&smsText=" + body;
     string targeturl = url.Trim().ToString();
     try
     {
  HttpWebRequest hr = (HttpWebRequest)WebRequest.Create(targeturl);
  hr.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)";
  hr.Method = "GET";
  hr.Timeout = 30 * 60 * 1000;
  WebResponse hs = hr.GetResponse();
  Stream sr = hs.GetResponseStream();
  StreamReader ser = new StreamReader(sr, Encoding.Default);
  return GetMobileMSMStatus(ser.ReadToEnd());
     }
     catch (Exception ex)
     {
  throw ex;
     }
 }
    }
}
