需要在使用TcpClient的类上实现终结器吗？

using System;
using System.Net.Sockets;

public class MyTcpClient : IDisposable
{
    private TcpClient _tcpClient;

    public MyTcpClient(string host, int port)
    {
        _tcpClient = new TcpClient(host, port);
    }

    public void Dispose()
    {
        Dispose(true);
        GC.SuppressFinalize(this);
    }

    protected virtual void Dispose(bool disposing)
    {
        if (disposing)
        {
            _tcpClient?.Close();
            _tcpClient?.Dispose();
        }
    }
}
