切断された IP アドレスに接続するときにソケット接続タイムアウトを短縮するにはどうすればよいですか?

try
{
    m_clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
    IPAddress ip = IPAddress.Parse(serverIp);
    int iPortNo = System.Convert.ToInt16(serverPort);
    IPEndPoint ipEnd = new IPEndPoint(ip, iPortNo);
    m_clientSocket.Connect(ipEnd);
    if (m_clientSocket.Connected)
    {
        lb_connectStatus.Text = "Connection Established";
        WaitForServerData();
    }
}
catch (SocketException se)
{
    lb_connectStatus.Text = "Connection Failed";
    MessageBox.Show(se.Message);
}

Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

// Set connection timeout (5 seconds)
IAsyncResult result = socket.BeginConnect(sIP, iPort, null, null);

bool success = result.AsyncWaitHandle.WaitOne(5000, true); // 5000 milliseconds = 5 seconds

if (socket.Connected)
{
    socket.EndConnect(result);
    // ... proceed with connection ...
}
else
{
    // Crucial: Close the socket to release resources
    socket.Close();
    throw new ApplicationException("Failed to connect to server.");
}
