c＃有没有办法在类本身之外不可用的类中对象的属性？

Question

我正在寻找一种在类中拥有一个对象，并使该对象在班级本身之外的不可分割的（对象本身及其属性），但外部仍然可见。

internal class Room
{
    public string Description { get; set; }
}

internal class RoomController
{
    public Room Room { get; private set; }
    
    public RoomController()
    {
        Room = new Room();
    }

    //Edit the room inside this class
}

internal class Foo
{
    public void SomeMethod()
    {
        RoomController rc = new RoomController();
        
        rc.Room.Description = "something";   // This should not be allowed 
        string roomDesc = rc.Room.Description;   // This should be fine   
    }
}

有可能吗？关于这个问题，我找不到任何东西，所以如果有人有任何想法，我会很感激。

提前致谢！

您可以定义一个仅揭示您想要公开的位的接口：

internal interface IReadonlyRoom
{
  string Description { get; }  //note only getter exposed
}

internal class Room : IReadonlyRoom
{
    public string Description { get; set; }
}

internal class RoomController
{
    private Room _room;

    public IReadonlyRoom Room => _room;

    public RoomController()
    {
        _room = new Room();
    }

    //edit using _room
}
