短信发送

中国短信网的发送接口：

    /// <summary>
    /// 发送短信并返回结果
    /// </summary>
    /// <param name="hm">号码</param>
    /// <param name="nr">内容</param>
    /// <returns></returns>
    public static String fs(string hm, string nr)
    {
        StringBuilder sbTemp = new StringBuilder();

        sbTemp.Append("uid=*****&pwd=*****&mobile=" + hm + "&content=" + nr);
        byte[] bTemp = System.Text.Encoding.GetEncoding("GBK").GetBytes(sbTemp.ToString());
        String postReturn = Define.doPostRequest("http://http.c123.com/tx/", bTemp);
        return postReturn;
    }
    //POST方式发送得结果
    public static String doPostRequest(string url, byte[] bData)
    {
        System.Net.HttpWebRequest hwRequest;
        System.Net.HttpWebResponse hwResponse;

        string strResult = string.Empty;
        try
        {
            hwRequest = (System.Net.HttpWebRequest)System.Net.WebRequest.Create(url);
            hwRequest.Timeout = 5000;
            hwRequest.Method = "POST";
            hwRequest.ContentType = "application/x-www-form-urlencoded";
            hwRequest.ContentLength = bData.Length;

            System.IO.Stream smWrite = hwRequest.GetRequestStream();
            smWrite.Write(bData, 0, bData.Length);
            smWrite.Close();
        }
        catch (System.Exception err)
        {
            WriteErrLog(err.ToString());
            return strResult;
        }

        //get response
        try
        {
            hwResponse = (HttpWebResponse)hwRequest.GetResponse();
            StreamReader srReader = new StreamReader(hwResponse.GetResponseStream(), Encoding.ASCII);
            strResult = srReader.ReadToEnd();
            srReader.Close();
            hwResponse.Close();
        }
        catch (System.Exception err)
        {

        }

        return strResult;
    }

        System.Diagnostics.Trace.WriteLine(strErr);
    }

 这个网站只能接收到别人回复的短信，不能设置接收的号码，跟我的需求不同，就没继续使用下去，过几天我用其他的接口实现了短信查询功能后，再贴出来…
