NamedPipeClientStream.Write没有返回

Question

我正在尝试开发两个应用程序，它们在运行时通过命名管道相互通信，服务器应用程序创建两个管道，一个用于向客户端发送数据，另一个用于从中接收数据。

使用Task在另一个线程中处理写入和读取操作，在创建管道或连接它们时没有问题。

当客户端尝试在管道中写入数据时出现问题，一旦调用Write方法，执行就会停止。

                    OutPipe.WaitForConnection();
                    InPipe.WaitForConnection();
                }
                CanReceiveMessages.WaitOne(); //The server start reading data only when signaled by the client, so that there is always data to read.
                MessagesSemaphore.WaitOne(); //The methods of the class can be run only by one thread at a time, a Semaphore is used to regulate access.
