通过tcp网络流读/写字符串

Question

我已经通过TCP套接字多次在应用程序之间发送二进制数据,但从未使用过字符串.陷入了打算这样做的问题.这是我得到的:

        TcpClient tcpClient = new TcpClient("localhost", port);

        //Connects fine
        NetworkStream ns = tcpClient.GetStream();
        StreamWriter sw = new StreamWriter(ns);

        //The code moves on but nothing seems to be sent unless I do
        //a sw.Close() after this line. That would however close the  
        //ns and prevent me from reading the response further down
        sw.Write("hello");

        //I am using a stream reader with ReadToEnd() on the tcpListener
        //which never receives the string from this piece of code

        //Since the above never actually send I get stuck here
        string response = new StreamReader(ns).ReadToEnd();

        sw.Close();
        tcpClient.Close();

如何在不关闭网络流的情况下发送字符串？ns.Flush()是我真正想要的.

你有一个sw.Flush(),应该工作.一个人WriteLine()也可能做到了.

但是当另一方做了ReadLine()时,你必须确保以换行结束.尝试WriteLine()而不是Write().

关闭StreamReader/Writer时要小心,它们也会关闭它们的底层流.
