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
我要评论
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
