我正在开发将连接到服务器的Windows Phone应用程序。当您按下登录按钮时，它通过使用ConnectAsync来做到这一点。但是，如果服务器已关闭，并且您想取消连接尝试，该怎么办？

这是当前的客户端代码，其中包括我最近尝试关闭套接字连接的最新信息。假定一旦知道如何关闭连接就可以轻松实现超时。

    private IPAddress ServerAddress = new IPAddress(0xff00ff00); //Censored my IP
    private int ServerPort = 13000;
    private Socket CurrentSocket;
    private SocketAsyncEventArgs CurrentSocketEventArgs;
    private bool Connecting = false;

            }
            UserData userdata = new UserData();
            userdata.Username = usernameBox.Text;
            userdata.Password = passwordBox.Password;

            Connecting = ConnectToServer(userdata);
        }
        catch (Exception exception)
        {
            Dispatcher.BeginInvoke(() => MessageBox.Show("Error: " + exception.Message));
        }
    }

    private bool ConnectToServer(UserData …
