通过TCP订阅，反序列化每个接收的JSON行

Question

tcp_connection = tcp_connect('localhost', 20060) 
// the server will always send responses on one line. 
tcp_connection.on('line', function (line) { 
json = json.decode(line) 
if(json.result == "success") { 
    // etc, etc, etc. 
} 
}) 
tcp_connection.write("/api/subscribe?source={sourceName}&key={key}&show_previous={true|false}") //stream API request 

嗯，这是我得到的伪代码，我不知道如何在C＃中重写它。我有这样的事情：

TcpClient connection = new TcpClientWithTimeout(host, 20059, 20000).Connect(); 
NetworkStream stream = connection.GetStream(); 

我不知道如何更换“tcp_connection.on”，所以，我已经订阅了TCP后，每行我得到被使用json.decode转换成字符串（万一有帮助，响应格式为：

{"result":"success/error","source": "{source}","success":{"time": TIME RECEIVED,"line":"RECEIVED LINE"}})

喜欢的东西：

TcpClient connection = new TcpClientWithTimeout(host, 20059, 20000).Connect(); 
NetworkStream stream = connection.GetStream(); 
var reader = new StreamReader(stream); 
var writer = new StreamWriter(stream); 
var line = reader.ReadLine(); 
if (line != "success") 
    throw new InvalidOperationException("Failed to connect"); 

writer.WriteLine(@"/api/subscribe?source={sourceName}&key={key}&show_previous={true|false}"); 

之后，你刚开始读线：

while ((line = reader.ReadLine()) != null) 
{ 
    Console.WriteLine("Got event: " + line); 
}
