拥有dotnet core 2.0.0 Socket.Listen()支持UNIX域套接字

Question

根据 https://github.com/dotnet/corefx/issues/10981，我从corefx/src/System.Net.Sockets/tests/FunctionalTests/UnixDomainSocketTest复制了实现.cs并在本地使用它，如下所示。（我在 Ubuntu 上使用 dotnet core 2.0.0）

Socket s = new Socket(AddressFamily.Unix, SocketType.Dgram, ProtocolType.Unspecified);
Console.WriteLine(s.SendBufferSize);
Console.WriteLine(s.ReceiveBufferSize);
var unixSocket = "./my.sock.1";
var ep = new UnixDomainSocketEndPoint(unixSocket);
Console.WriteLine(ep.AddressFamily);
try
{
    System.IO.File.Delete(unixSocket);
    s.Bind(ep);
    s.Listen(5);  // **Operation not supported**
    while(true)
    {
        var newS = s.Accept();
        byte[] content = new byte[1000];
        var result = s.Receive(content);
        Console.WriteLine(result);
        Console.WriteLine(Encoding.Default.GetString(content));
        newS.Close();
    }
}
catch(Exception e)
{
    Console.WriteLine(e.Message);
    Console.WriteLine(e.StackTrace);
    s.Close();
}

例外情况如下：

Operation not supported
   at System.Net.Sockets.Socket.UpdateStatusAfterSocketErrorAndThrowException(SocketError error, String callerName)
   at System.Net.Sockets.Socket.Listen(Int32 backlog)
   at test01.Program.Main(String[] args) in /home/nonstatic/code/temp/test01/Program.cs:line 106

是否有任何解决方案或解决方法可以让dotnet core在Linux中构建域套接字服务器？谢谢！

看起来@stephentoub回复了您相应的GitHub问题的答案。

您是否尝试过 SocketType.Stream 而不是 SocketType.Dgram？
