Question

手动断开套接字后出现异常：

描述符不是套接字UnityEngine.Debug：Log（Object） ClientTCP：OnReceive（）（位于Assets / Scripts / ClientTCP.cs：95） ClientTCP：ConnectCallback（IAsyncResult）（在资产/脚本/ClientTCP.cs:37）System.Net.Sockets.Worker：Connect（）

我认为当启用“ closed”标志时，我的“ while（！closed）OnReceive（）”周期应该停止。

当该方法获得0字节时，它应显示“与服务器断开连接”并将该标志设置为True。

实际上就是这样：我在Unity中收到“与服务器断开连接”消息。

我没有更改代码中的任何内容，但现在更改为“ _clientSocket.Disconnect（true）;”我遇到了提到的异常。

您能看看我在做什么错吗？

public class ClientTCP : MonoBehaviour
{
    public static Socket _clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
    private byte[] _asyncbuffer = new byte[1024];
    private bool closed;

    public string IP_ADDRESS;
    public int PORT;

    public void ConnectToServer()
    {
        closed = false;
        Debug.Log("Connecting to server...");
        _clientSocket.BeginConnect(IP_ADDRESS, PORT, new AsyncCallback(ConnectCallback), _clientSocket);
    }

    private void ConnectCallback(IAsyncResult asyncResult)
    {
        _clientSocket.EndConnect(asyncResult);
        while (!closed)
        {
            OnReceive(); //Line 37
        }

    }

    public void DisconnectFromServer()
    {
        _clientSocket.Disconnect(true);

        closed = true;
    }

    private void OnReceive()
    {
        byte[] _sizeinfo = new byte[4];
        byte[] _receivedbuffer = new byte[1024];

        int totalread = 0, currentread = 0;

        try
        {
            currentread = totalread = _clientSocket.Receive(_sizeinfo); //Line 58

            if (totalread <= 0)
            {
                Debug.Log("Disconnected from server");
                closed = true;
            }
            else
            {
                while (totalread < _sizeinfo.Length && currentread > 0)
                {
                    currentread = _clientSocket.Receive(_sizeinfo, totalread, _sizeinfo.Length - totalread, SocketFlags.None);
                    totalread += currentread;
                }

                int messagesize = 0;
                messagesize |= _sizeinfo[0];
                messagesize |= (_sizeinfo[1] << 8);
                messagesize |= (_sizeinfo[2] << 16);
                messagesize |= (_sizeinfo[3] << 24);

                byte[] data = new byte[messagesize];

                totalread = 0;
                currentread = totalread = _clientSocket.Receive(data, totalread, data.Length - totalread, SocketFlags.None);

                while (totalread < messagesize && currentread > 0)
                {
                    currentread = _clientSocket.Receive(data, totalread, data.Length - totalread, SocketFlags.None);
                    totalread += currentread;
                }

                ClientHandleNetworkData.HandleNetworkInformation(data);
            }
        }
        catch (Exception ex)
        {
            Debug.Log(ex.Message); //Line 95, here the exception is thrown
            closed = true;
        }
    }

ex.ToString（）提供以下内容：

System.Net.Sockets.SocketException：描述符不是套接字
在System.Net.Sockets.Socket.Receive（System.Byte []缓冲区）[0x00000] 在ClientTCP.OnReceive（）的：0中：[0x0001e]在 /Users/nidere/Projects/Unity/OverWaste/Assets/Scripts/ClientTCP.cs:58 UnityEngine.Debug：Log（Object）ClientTCP：OnReceive（）（在资产/脚本/ClientTCP.cs：95） ClientTCP：ConnectCallback（IAsyncResult）（在资产/脚本/ClientTCP.cs:37）System.Net.Sockets.Worker：Connect（）

58行是：

currentread = totalread = _clientSocket.Receive(_sizeinfo);

“描述符不是套接字”异常
