试图以访问权限禁止的方式访问套接字.为什么? [英] An attempt was made to access a socket in a way forbidden by its access permissions. Why?

问题描述

 private void StartReceivingData(string ipAddress, int iPort)
    {
        try
        {
            if (!_bContinueReciving)
            {
                //initializeMainSocket(ipAddress, iPort);
                _mSocket = new Socket(AddressFamily.InterNetwork, SocketType.Raw, ProtocolType.IP);//<------HERE IS RAISED THE EXCEPTION
                _mSocket.Bind(new IPEndPoint(IPAddress.Parse(ipAddress), iPort));
                //  _mSocket.Bind(new IPEndPoint(IPAddress.Loopback, iPort));
                _mSocket.SetSocketOption(SocketOptionLevel.IP, SocketOptionName.HeaderIncluded, true);
                _mSocket.IOControl(IOControlCode.ReceiveAll, new byte[4] { 1, 0, 0, 0 }, new byte[4] { 0, 0, 0, 0 });
                //var 1
                _mSocket.BeginReceive(_buffReceivedData, 0, _buffReceivedData.Length, SocketFlags.None,
                                     new AsyncCallback(OnReceive), null);
                initializeLocalSocket();
            }
            else
            {
                _bContinueReciving = false;
                _mSocket.Close();
            }
        }
        catch (Exception exception)
        {
            Debug.WriteLine(exception);
        }
    }

我不明白为什么......它起作用了，但现在不起作用了.有人可以帮助我吗?我正在使用 vlc 进行流式传输，但我不想接收数据包，做一些报告，然后将本地重新流式传输到播放器

I don't understand why...it worked and now it doesn't. could someone help me? i am streaming with vlc, and i wan't to receive the packets, do some reports, and then restream local to a player

推荐答案

很可能套接字由某个进程持有.使用 netstat -o 查找哪个.

Most likely the socket is held by some process. Use netstat -o to find which one.
