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
{

    /// <summary>返回发送短信的状态说明
    ///
    /// </summary>
    /// <param name="str"></param>
    /// <returns></returns>
    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;
    }
    /// <summary>发送手机短信
    ///
    /// </summary>
    /// <param name="mobile">手机号码,多个手机号以,号相隔</param>
    /// <param name="body">短信内容</param>
    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;
        }
    }
}
