Question

我正在尝试在Unity 2017.4.10f1中使用ClientWebSocket类，并且得到了ObjectDisposedException。

这是我正在使用的代码：

    private async void ContinousReceiveAsync()
    {
        Debug.Log("Receiving...");

        while (State == WebSocketState.Open)
        {
            List<byte> _buffer = new List<byte>();
            WebSocketReceiveResult result = null;

            do
            {
                ArraySegment<byte> _segment = new ArraySegment<byte>(new byte[1024]);
                result = await _socket.ReceiveAsync(_segment, CancellationToken.None);

                switch (result.MessageType)
                {
                    case WebSocketMessageType.Text:
                        _buffer.AddRange(_segment.Array);
                        if(result.EndOfMessage)
                            TextRecieved(Encoding.UTF8.GetString(_buffer.ToArray()));
                        break;

                    case WebSocketMessageType.Binary:
                        byte[] _data = new byte[result.Count];
                        Array.Copy(_segment.Array, _data, result.Count);
                        _buffer.AddRange(_data);

                        if (result.EndOfMessage)
                            BinaryRecieved(_buffer.ToArray());
                        break;

                    case WebSocketMessageType.Close:
                        SocketCleanUp(result?.CloseStatus);

                        if (AutoReconnect)
                        {
                            Reconnect();
                        }
                        break;

                    default:
                        Debug.LogError("[Madapter.Websocket] Unknown WebSocketMessageType");
                        break;
                }
            }
            while (!result.EndOfMessage);
        }

        Debug.Log("Stopped Receiving");
    }

ReceiveAsync抛出对象System.Net.Sockets.NetworkStream的ObjectDisposedException。当我尝试通过websocket发送邮件时，这种情况只会立即发生。

这是Send函数：

    public async Task SendTextAsync(string msg)
    {
        if(State == WebSocketState.Open)
        {
            ArraySegment<byte> buffer = new ArraySegment<byte>(Encoding.UTF8.GetBytes(msg));
            await SendAsync(buffer, WebSocketMessageType.Text);
        }
    }

    public async Task SendBinaryAsync(byte[] data)
    {
        if (State == WebSocketState.Open)
        {
            ArraySegment<byte> buffer = new ArraySegment<byte>(data);
            await SendAsync(buffer, WebSocketMessageType.Binary);
        }
    }

    private async Task SendAsync(ArraySegment<byte> buffer, WebSocketMessageType type)
    {
        await _socket.SendAsync(buffer, type, true, CancellationToken.None);
    }

错误：
