這段C#代碼用于檢測遠程計算機的3389端口是否處理打開狀態(tài)，可以根據實際需要設置其它端口

        static void Main(string[] args)

        }
 
  
 
        public static void GetTcpConnections()
        {
            //code from http://www.sharejs.com/codes
 
            IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
        
            TcpConnectionInformation[] connections = properties.GetActiveTcpConnections();
            foreach (TcpConnectionInformation t in connections)
            {
                Console.Write("Local endpoint: {0} ", t.LocalEndPoint.ToString());
