c＃中的Java内部类 [英] Java inner classes in c#

问题描述

我有以下Java代码：

I have the following Java code:

public class A {
    private int var_a = 666;

    public A() {
        B b = new B();
        b.method123();
        System.out.println(b.var_b);
    }

    public class B {
        private int var_b = 999;

        public void method123() {
            System.out.println(A.this.var_a);           
        }
    }
}

产生666和999。现在，我已经尝试在c＃中设置类似的代码，但似乎无法实现相同的功能。如果是这种情况，你在c＃编程时通常会如何达到类似的效果？

Which yields 666 and 999. Now, I've tried to set up similar code in c#, but it seems that it is not possible to accomplish the same. If that's the case, how you usually achieve a similar effect when programming in c#?

推荐答案

你需要让内部课采取外部类的实例作为构造函数参数。 （这是Java编译器实现内部类的方式）

You need to make the inner class take an instance of the outer class as a constructor parameter. (This is how the Java compiler implements inner classes)
