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。
