Question

如果字符超过136，我们希望将邮件拆分为多条（短信）短信。

但我们也希望确保第二条消息在第一条消息到达第三条消息之后到达。

到目前为止，从我们完成的几项测试来看，它似乎都是这样工作的，但要确保我们仍然希望延迟大约3秒左右。

是Thread.Sleep正确的方法吗，还是有其他解决方案而不是添加延迟？

这是代码：

    // Split message to send them as individual text messages
    string[] messages = splitMessage(request["message"], 132);
    for (int i = 0; i < messages.Length; i++)
    {
        HttpWebRequest _wr = (HttpWebRequest)WebRequest.Create(url);

        // Use the CredentialCache so you can attach the authentication to the request
        CredentialCache mycache = new CredentialCache { { new Uri(url), "Basic", new NetworkCredential(_username, _password) } };

        // use Basic Authentication
        _wr.Credentials = mycache;
        _wr.Method = "POST";
        _wr.ContentType = "application/json";
        _wr.Timeout = -1;   // not sure if necessary but it's not harmful

        // _data variable holds the data to be pushed to the server in the request.
        // this piece of data holds the request to send a text message from the application
        string _data = "{\"outboundSMSMessageRequest\":" +
                        "{\"address\": \"" + formatedAddress + "\",\"requestId\": \"" + request["requestId"] + "\"" +
                        ",\"outboundSMSTextMessage\": \"" + messages[i] + "\",\"senderAddress\": \"" + request["sender"] + "\"" +
                        _optional + "}}";

        //get a reference to the request-stream, and write the POST data (_data) to it
        using (var s = new StreamWriter(_wr.GetRequestStream()))
        {
                s.Write(_data);
        }

        //get response-stream, and use a streamReader to read the content
        try
        {
                HttpWebResponse _response = (HttpWebResponse)_wr.GetResponse();
        }
        catch (WebException ex)
        {
                using (StreamWriter file = new StreamWriter(@"D:\WEB\SMS\jsonResponse.txt", true))
                {
                        file.WriteLine("No good");
                }
                // Log exception and throw as for GET example above
                Trace.WriteLine("No good");
                Trace.WriteLine(ex);
        }

        using (Stream s = _wr.GetResponse().GetResponseStream())
        {
                using (StreamReader sr = new StreamReader(s))
                {
                        var jsonData = sr.ReadToEnd();
                        Trace.WriteLine("Server response: " + jsonData);
                        //decode jsonData with javascript serializer

                        using (StreamWriter file = new StreamWriter(@"D:\WEB\SMS\jsonResponse.txt", true))
                        {
                                file.WriteLine("Server response: " + jsonData);
                        }
                }
        }
}

我宁愿查看你的短信发送器API的文档，因为它可能写在那里，他们不保证短信的顺序 - 他们可以有内部队列，服务器的响应可能意味着他们已经排除了这些信息，而不是他们已经交付了它。在这种情况下，添加3秒，5秒甚至10秒的延迟不会有帮助。
