如何在c#中获取某个进程正在连接的in

using System;
using System.Diagnostics;
using System.Net.NetworkInformation;

class Program
{
    static void Main()
    {
        int processId = 1234; // 替换为目标进程的PID

        Process process = Process.GetProcessById(processId);
        IPGlobalProperties ipProperties = IPGlobalProperties.GetIPGlobalProperties();
        TcpConnectionInformation[] tcpConnections = ipProperties.GetActiveTcpConnections();

        foreach (TcpConnectionInformation connection in tcpConnections)
        {
            if (connection.State == TcpState.Established && connection.ProcessId == process.Id)
            {
                Console.WriteLine("Local Address: {0}:{1}", connection.LocalEndPoint.Address, connection.LocalEndPoint.Port);
                Console.WriteLine("Remote Address: {0}:{1}", connection.RemoteEndPoint.Address, connection.RemoteEndPoint.Port);
                Console.WriteLine();
            }
        }
    }
}
