用C＃进行json调用

在您的代码中，您不会获得HttpResponse，因此您将看不到服务器端将您发回的内容。

您需要获得与获取（发出）请求类似的响应。所以

public static bool SendAnSMSMessage(string message){  var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://api.pennysms.com/jsonrpc");  httpWebRequest.ContentType = "text/json";  httpWebRequest.Method = "POST";  using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))  {    string json = "{ "method": "send", " +"  "params": [ " +"  "IPutAGuidHere", " +"  "msg@MyCompany.com", " +"  "MyTenDigitNumberWasHere", " +"  "" + message + "" " +"  ] " +"}";    streamWriter.Write(json);  }  var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();  using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))  {    var responseText = streamReader.ReadToEnd();    //Now you have your response.    //or false depending on information in the response    return true;          }}

我在pennysms文档中还注意到，他们期望内容类型为“ text / json”，而不是“ application /
json”。这可能没有什么区别，但是如果它不起作用，则值得尝试。
