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
usingSystem;
usingSystem.Collections.Generic;
usingSystem.Text;
usingSystem.Net.NetworkInformation;
namespacetest
{
classProgram
{
staticvoidMain(string[]args)
{
GetTcpConnections();
}
publicstaticvoidGetTcpConnections()
{
IPGlobalPropertiesproperties=IPGlobalProperties.GetIPGlobalProperties();
TcpConnectionInformation[]connections=properties.GetActiveTcpConnections();
foreach(TcpConnectionInformationtinconnections)
{
Console.Write("Localendpoint:{0}",t.LocalEndPoint.ToString());
Console.Write("Remoteendpoint:{0}",t.RemoteEndPoint.ToString());
Console.WriteLine("{0}",t.State);
}
Console.WriteLine();
Console.ReadLine();
}
}
}
运行结果如下：
Localendpoint:127.0.0.1:1025Remoteendpoint:127.0.0.1:1026Established Localendpoint:127.0.0.1:1026Remoteendpoint:127.0.0.1:1025Established Localendpoint:127.0.0.1:1028Remoteendpoint:127.0.0.1:16992CloseWait Localendpoint:127.0.0.1:1110Remoteendpoint:127.0.0.1:4900Established Localendpoint:127.0.0.1:2754Remoteendpoint:127.0.0.1:1110CloseWait Localendpoint:127.0.0.1:2762Remoteendpoint:127.0.0.1:1110CloseWait Localendpoint:127.0.0.1:2773Remoteendpoint:127.0.0.1:1110CloseWait Localendpoint:127.0.0.1:2913Remoteendpoint:127.0.0.1:1110CloseWait Localendpoint:127.0.0.1:3014Remoteendpoint:127.0.0.1:1110CloseWait Localendpoint:127.0.0.1:3531Remoteendpoint:127.0.0.1:1110CloseWait Localendpoint:127.0.0.1:4012Remoteendpoint:127.0.0.1:1110CloseWait Localendpoint:127.0.0.1:4900Remoteendpoint:127.0.0.1:1110Established
