Question

我正在尝试将C＃.Net项目转换为Mono。 NamedPipeServerStream＆amp; NamedPipeClientStream类在Mono中不支持并抛出Unhandle异常。你能帮我一个人吗？

代码：

class Program
{
    static string _PipeName = "testPipe";
    static void Main(string[] args)
    {

        ListenForPipeServer();
    }

    static void ListenForPipeServer()
    {
        using (NamedPipeServerStream pipeServer = new NamedPipeServerStream(
                          _PipeName,
                          PipeDirection.InOut,
                          2,
                          PipeTransmissionMode.Message,
                          PipeOptions.None

                          ))
        {
            StreamReader sr = new StreamReader(pipeServer);
            StreamWriter sw = new StreamWriter(pipeServer);


            do
            {
                try
                {
                    pipeServer.WaitForConnection();
                    sw.WriteLine("Testing");
                    sw.Flush();
                    pipeServer.WaitForPipeDrain();
                    Console.WriteLine(sr.ReadLine());

                }
                catch (Exception)
                {

                    throw;
                }
                finally
                {

                    pipeServer.WaitForPipeDrain();
                    if (pipeServer.IsConnected) pipeServer.Disconnect();
                }

            } while (true);

        }
    }



}

Answer 1

唯一的问题是，当C＃代码访问管道时，您正在使用的名为“testPipe”的管道不存在。如果您首先运行命令mkfifo testPipe（在unix上），然后运行以下C＃代码，它应该可以工作。

Mono中的NamedPipeServerStream
