    {

Answer 1

为什么不在Furniture 类中声明MyProperty 然后覆盖它？

例子:

public class Furniture
{
    public virtual int MyProperty {get;}
}

public class HomeFurniture : Furniture
{
    public override int MyProperty
    {
        get
        {
            return 9;
        }
    }
}

public class OfficeFurniture : Furniture
{
    public override int MyProperty
    {
        get
        {
            return 10;
        }
    }
}
