c# - 从 c# windows 应用程序发送短信？

Question

可能这不是一个真正的问题，但我需要帮助，因为我厌倦了这样做。我想从我的 c# windows 应用程序发送短信，我阅读了很多博客，我也找到了一些代码，但这不起作用。我指的是这个链接使用 API

http://ubaid.tk/api-usage/

我的代码是：

public void send(string uid, string password, string message, string no)
    {
        try
        {
            HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create("http://ubaid.tk/sms/sms.aspx?uid=" + uid + "&pwd=" + password + "&msg=" + message + "&phone=" + no + "&provider=fullonsms");
            HttpWebResponse myResp = (HttpWebResponse)myReq.GetResponse();
            System.IO.StreamReader respStreamReader = new System.IO.StreamReader(myResp.GetResponseStream());
            string responseString = respStreamReader.ReadToEnd();
            respStreamReader.Close();
            myResp.Close();
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.ToString());
            string msg = ex.ToString();
        }
    }

但它给了我这个错误：

System.Net.WebException: The operation has timed out at system.Net.HttpWebRequest.GetResponse()

我不知道如何解决这个错误。我需要帮助，如果有人有任何其他更好的链接，请分享。

非常感谢您的帮助。

所以看看短信网站，它说他们的服务被 IP 封锁了。它没有说明 IP 块是来自手机公司还是来自 ISP，所以这可能是个问题。它还说他们经历了停机时间，因此可能是他们的服务器停机了。也可能是他们的服务器很慢，而您的程序超时太快了。
