Windows命名管道无法通过网络工作？

    NamedPipeClientStream pipeStream = new NamedPipeClientStream(\"default-PC\",\"mypipe\");

    pipeStream.Connect();
    BinaryWriter sw = new BinaryWriter(pipeStream);
    sw.Write((byte[]) data);

    NamedPipeServerStream pipeStream = new NamedPipeServerStream(\"mypipe\");
    byte[] dataAll = null;
    pipeStream.WaitForConnection();
    dataAll = new BinaryReader(pipeStream).ReadBytes(1024 * 1000 * 512);
