C#从另一个类访问变量，而不重构该类

如何从另一个类访问变量而不重建它？

1级：

namespace Server.world
{
    public class WorldData
    {
        private entitys.Player[] Players = new entitys.Player[Convert.ToInt16(ConfigurationManager.AppSettings["maxplayers"])];
        public entitys.Player this[int i]
        {
            get { return Players[i]; }
            set { Players[i] = value; }
        }
    }
}

类#2：构造worldData类：

namespace Server
{
    class StartUp
    {
        public Server.tcpserver.TcpServer ListenerTcp = new Server.tcpserver.TcpServer();
        public world.WorldData WorldData = new world.WorldData();
        /// <summary>
        /// Server start function
        /// </summary>
        public void Start()
        {
            string rootFolder = ConfigurationManager.AppSettings["rootfolder"];
            if (!Directory.Exists(rootFolder))
            {
                Directory.CreateDirectory(rootFolder);
                string pathString = Path.Combine(rootFolder, "world");
                Directory.CreateDirectory(pathString);
            }
            ListenerTcp.StartListening();
            //No code below this point
        }
    }
}

3级：

namespace Server.tcpserver
{
    class TcpServer
    {
        int counter = 0;
        public void StartListening()
        {
            IPAddress ipAddress = Dns.GetHostEntry("127.0.0.1").AddressList[0];
            TcpListener serverSocket = new TcpListener(8888);
            TcpClient clientSocket = default(TcpClient);
            serverSocket.Start();
            counter = 0;
            while (true)
            {
                counter += 1;
                clientSocket = serverSocket.AcceptTcpClient();
                Server.client.Client Client = new Server.client.Client(clientSocket);
                Console.WriteLine("Player Connected!");
                //get world playerdata here
            }
        }
    }
}

我该怎么做？我到处找都找不到，

C#从另一个类访问变量，而不重构该类

一种方法是，您可以提供一个构造函数，该构造函数接受WorldData的实例，甚至是将WorldData公开为属性的StartUp实例。

public class TcpServer
{
    int counter = 0;
    private StartUp startUp:
    public TcpServer(StartUp startUp)
    {
        this.startUp = startUp;
    }
    public void StartListening()
    {
        // ...
        var worldData = this.startUp.WorldData;     // <--- !!!
        // ...
    }
    // ...
}

现在我还将使用StartUp的构造函数来初始化TcpServer:

public class StartUp
{
    public StartUp()
    {
        WorldData = new world.WorldData();
        ListenerTcp = new Server.tcpserver.TcpServer( this );  // <--- !!!
    }
    public Server.tcpserver.TcpServer ListenerTcp;
    public world.WorldData WorldData;
    // ...
}
