Question

我正在寻找一种使用＆＃34;来访问嵌套公共类的方法。＆＃34;运营商。所以对于下面的例子，我想访问嵌套在House类中的Kitchen类。

   public class House{

        public class Kitchen{
            //some public properties
            public int numberOfChairs {get; set;}
        }

    }


    //Now want to access Kitchen in another class.
    public class Main{
            House newHouse = new House();
            newHouse.Kitchen.numberOfChairs = 5;
    }


any hint and help is much appreciate.

Answer 1

您需要创建一个Kitchen实例。类似的东西：

House.Kitchen newKitchen = new House.Kitchen();
newKitchen.numberOfChairs = 5;

根据回复更新答案：

在这种情况下，你的House类，也需要有一个Kitchen成员。

public class House{

    public class Kitchen{
        //some public properties
        public int numberOfChairs {get; set;}
    }

    public House() {
      kitchen = new Kitchen();
    }

    public Kitchen kitchen {get; set;}

}

public class Main{
    House newHouse = new House();
    newHouse.kitchen.numberOfChairs = 5;
}

Answer 2

看看这个link。话虽这么说，你为什么要窝这个班？从您想要使用它的方式以及您已公开的事实来看，为什么不使用Kitchen类型的财产？

Answer 3

现在，您只声明了一个嵌套类。你的房子里没有那个班级的实例。就个人而言，我认为你甚至不需要一个嵌套的类。这可能是一个普通的课程。但是你需要一个实例：

public class House{

    public class Kitchen{
        //some public properties
        public int numberOfChairs {get; set;}
    }

    public Kitchen TheKitchen { get; set; }

}


//Now want to access Kitchen in another class.
public class Main{
        House newHouse = new House();
        newHouse.TheKitchen = new House.Kitchen();   
        newHouse.TheKitchen.numberOfChairs = 5;
}

Answer 4

在您的House类中添加Kitchen属性，以便您可以从House访问Kitchen的实例。

public class House{
    public Kitchen KitchenProp { get; set; }
    public class Kitchen{
            //some public properties
            public int numberOfChairs {get; set;}
        }
    }


    //Now want to access Kitchen in another class.
    public class Main{
            House newHouse = new House();
            newHouse.KitchenProp = new Kitchen();
            newHouse.KitchenProp.numberOfChairs = 5;
    }
