C#检测远程计算机端口是否打开的方法

本文实例讲述了c#检测远程计算机端口是否打开的方法。分享给大家供大家参考。具体分析如下：

这段c#代码用于检测远程计算机的3389端口是否处理打开状态，可以根据实际需要设置其它端口

using system;
using system.collections.generic;
using system.text;
using system.net.networkinformation;
namespace test
{
  class program
  {
    static void main(string[] args)
    {
      gettcpconnections();
    }
    public static void gettcpconnections()
    {
      ipglobalproperties properties = ipglobalproperties.getipglobalproperties();
      tcpconnectioninformation[] connections = properties.getactivetcpconnections();
      foreach (tcpconnectioninformation t in connections)
      {
        console.write("local endpoint: {0} ", t.localendpoint.tostring());
        console.write("remote endpoint: {0} ", t.remoteendpoint.tostring());
        console.writeline("{0}", t.state);
      }
      console.writeline();
      console.readline();
    }
  }
}

运行结果如下：

local endpoint: 127.0.0.1:1025 remote endpoint: 127.0.0.1:1026 established
local endpoint: 127.0.0.1:1026 remote endpoint: 127.0.0.1:1025 established
local endpoint: 127.0.0.1:1028 remote endpoint: 127.0.0.1:16992 closewait
local endpoint: 127.0.0.1:1110 remote endpoint: 127.0.0.1:4900 established
local endpoint: 127.0.0.1:2754 remote endpoint: 127.0.0.1:1110 closewait
local endpoint: 127.0.0.1:2762 remote endpoint: 127.0.0.1:1110 closewait
local endpoint: 127.0.0.1:2773 remote endpoint: 127.0.0.1:1110 closewait
local endpoint: 127.0.0.1:2913 remote endpoint: 127.0.0.1:1110 closewait
local endpoint: 127.0.0.1:3014 remote endpoint: 127.0.0.1:1110 closewait
local endpoint: 127.0.0.1:3531 remote endpoint: 127.0.0.1:1110 closewait
local endpoint: 127.0.0.1:4012 remote endpoint: 127.0.0.1:1110 closewait
local endpoint: 127.0.0.1:4900 remote endpoint: 127.0.0.1:1110 established

希望本文所述对大家的c#程序设计有所帮助。
