使用JSON POST（）

Question

我正在学习JSON，无法弄清下一步。我创建了一个JSON阅读器，并将我需要的数据添加到我的阅读器中，但是我现在如何使用这些数据实际发出POST（）请求？

这是我

private void PerformJSONPost() 
{ 
    var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://requestb.in/12frf661"); 
    httpWebRequest.ContentType = "application/json"; 
    httpWebRequest.Method = "POST"; 

    var jsonReader = JsonReaderWriterFactory.CreateJsonReader(Encoding.UTF8.GetBytes(@"{ ""Security"": { ""UsernameToken"": { ""Username"": ""redrobin"", ""Password"": ""fahidsma!"" } }"), new System.Xml.XmlDictionaryReaderQuotas()); 

}

这个语法的问题是，被张贴的唯一的事情就是：

System.Runtime.Serialization.Json.XmlJsonReader

 var request = WebRequest.CreateHttp(myUrl + "/" + uri); 
     request.Credentials = new NetworkCredential(myUserName, myPassword, myDomain); 
     request.ContentType = "application/json; charset=utf-8"; 
     request.Method = "POST"; 

     using (StreamWriter streamWriter = new StreamWriter(request.GetRequestStream())) 
     { 
      string jsonstring = JsonConvert.SerializeObject(myJsonobject, Formatting.Indented); 

      streamWriter.Write(jsonstring); 

      streamWriter.Flush(); 
     }
