本人親自試用可以用，現(xiàn)在的手機(jī)短信服務(wù)商很多，可以自己去找個(gè)，

我這個(gè)用的是齊魯商務(wù)通接口調(diào)用dotNet樣例.zip的接口，也是用的不錯(cuò)的，如果有需要的話我可以給提供

本例子用的就是他們提供的接口，簡(jiǎn)單操作，易用，就是個(gè)url地址的get傳值方式

代碼如下：

using System;
using System.Collections.Generic;
using System.Web;

using System.Web.UI.WebControls;
using System.Net;
using System.IO;
using System.Text;

/// <summary>

public static String sendMsg(string userName, string password, string mobile, string content)
{
String myParams = "commandID=3&username=" + userName + "&password=" + password + "&mobile=" + mobile + "&content=" + content;

String result = HttpInvoker.post(myParams);
return result;
}
public static String post(String myParams)
{
HttpWebRequest myReq = (HttpWebRequest)HttpWebRequest.Create("http://61.156.38.47:8080/CPDXT/SendSms");
myReq.Method = "POST";
myReq.ContentType = "application/x-www-form-urlencoded";
try
{
Stream myRequestStream = myReq.GetRequestStream();
StreamWriter myStreamWriter = new StreamWriter(myRequestStream, Encoding.Default);
myStreamWriter.Write(myParams);
myStreamWriter.Close();
myRequestStream.Close();

HttpWebResponse myHttpWebResponse = (HttpWebResponse)myReq.GetResponse();
if (myHttpWebResponse != null && myHttpWebResponse.StatusCode == HttpStatusCode.OK)
{
Stream myResponseStream = myHttpWebResponse.GetResponseStream();

StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.Default);

String result = myStreamReader.ReadToEnd();

//把數(shù)據(jù)從HttpWebResponse的Response流中讀出
myStreamReader.Close();

myResponseStream.Close();
return result;
}
else
{
return myHttpWebResponse == null ? "網(wǎng)絡(luò)異常" : "myHttpWebResponse.StatusCode";
}
}
catch (Exception ex)
{
return "網(wǎng)絡(luò)異常";
}

}

}

調(diào)用

String result = HttpInvoker.sendMsg("賬號(hào)", "密碼", 發(fā)送手機(jī), "親，你好，我們是鐵青旅行社，您的" + trade_no+TravelTitle + "已經(jīng)通過(guò)審核，請(qǐng)到支付寶確認(rèn)訂單，最后祝您旅游開(kāi)心！");
if ("return=0;".Equals(result))
{
Response.Write("<script type=＇text/javascript＇>alert(＇短信發(fā)送成功?。?;</script>");
}
else
{
Response.Write("<script type=＇text/javascript＇>alert(＇短信發(fā)送失?。。?;</script>");
}
//Response.Write("返回參數(shù)：" + result);
//Response.Write("<script type=＇text/javascript＇>alert(＇返回參數(shù):"+ result+"＇);</script>");
