C＃StreamSocket服务器与客户端通信的最大超时时间

Question

我从MSDN获得了以下代码。基本上，我想创建一个应用程序（客户端），它不断地等待来自服务器的命令来完成某项任务。由于服务器无法直接与客户端通信，因此客户端必须打开与服务器的连接，在服务器无限期地保持请求打开时请求某些内容，直到它使用该命令响应客户端。 reader.ReadLineAsync（）将阻止执行，直到服务器响应。 reader.ReadLineAsync（）是否有最大超时时间？或者有更好的方法吗？

try
{
    //Create the StreamSocket and establish a connection to the echo server.
    Windows.Networking.Sockets.StreamSocket socket = new Windows.Networking.Sockets.StreamSocket();

    //The server hostname that we will be establishing a connection to. We will be running the server and client locally,
    //so we will use localhost as the hostname.
    Windows.Networking.HostName serverHost = new Windows.Networking.HostName("localhost");

    //Every protocol typically has a standard port number. For example HTTP is typically 80, FTP is 20 and 21, etc.
    //For the echo server/client application we will use a random port 1337.
    string serverPort = "1337";
    await socket.ConnectAsync(serverHost, serverPort);

    //Write data to the echo server.
    Stream streamOut = socket.OutputStream.AsStreamForWrite();
    StreamWriter writer = new StreamWriter(streamOut);
    string request = "test";
    await writer.WriteLineAsync(request);
    await writer.FlushAsync();

    //Read data from the echo server.
    Stream streamIn = socket.InputStream.AsStreamForRead();
    StreamReader reader = new StreamReader(streamIn);
    string response = await reader.ReadLineAsync();
}
catch (Exception e)
{
//Handle exception here.            
}
