嵌套类 - 从父类调用嵌套类

Question

我有一个类,其中一个方法调用嵌套类.我想从嵌套类中访问父类属性.

public class ParentClass
{
    private x;
    private y;
    private z;

    something.something = new ChildClass();

    public class ChildClass
    {
        // need to get x, y and z;
    }
}

如何从子类中访问x,y和z？与引用父类有关,但如何做？

Answer 1

使用this关键字将对"self"的引用传递给ChildClass的构造函数.

public class ParentClass
{
    public X;
    public Y;
    public Z;

    // give the ChildClass instance a reference to this ParentClass instance
    ChildClass cc = new ChildClass(this);

    public class ChildClass
    {
        private ParentClass _pc;

        public ChildClass(ParentClass pc) {
            _pc = pc;
        }

        // need to get X, Y and Z;
        public void GetValues() {
            myX = _pc.X
            ...
        }
    }
}
