在C#中,如何检查TCP端口是否可用？

using System;
using System.Net.Sockets;

public class TcpPortChecker
{
    public static bool IsTcpPortAvailable(string ipAddress, int port)
    {
        using TcpClient tcpClient = new TcpClient();
        try
        {
            tcpClient.Connect(ipAddress, port);
            if (tcpClient.Connected)
            {
                tcpClient.Close();
                return false;
            }
        }
        catch (SocketException)
        {
            // ignored
        }
        return true;
    }
}

bool isPortAvailable = TcpPortChecker.IsTcpPortAvailable("127.0.0.1", 8080);
Console.WriteLine($"端口8080是否可用：{isPortAvailable}");
