问题描述

如何在子类的父类中调用函数(方法)?

how call function (method) in class parent in child class?

推荐答案

您当然需要对父类的引用.没有更好的描述，我们将无济于事.

You need a reference to the parent class of course. Without a MUCH better description, we can''t help much beyond that.

根据您的要求(虽然不是很清楚，但我会给它加一个提要)，您将看到这样的情况:

Hi,

Based on what you are asking (it wasn''t very clear but I will give it a bash), you will be looking at a scenario like this:

public class MyParentClass
{
    public virtual void SomeMethod()
    {
        /* do parent class stuff here */
    }
}

public class MyChildClass : MyParentClass
{
    public override void SomeMethod()
    {
        /* do child class stuff here */
        base.SomeMethod(); // <--- This will call the parent class method
    }
}

在子类中重写方法的任何时候，您都可以调用" base.SomeMethod()".

希望能对您有所帮助:)...

At any point in the overridden method in the child class you can call "base.SomeMethod()".

Hope that helps :)...

如果要在子类中调用父级的非静态方法，则该方法必须为public或protected:

If you want to call a none static method of the parent in a child class, the method must be public or protected:

base.MethodName();

如果要在父类中调用子级的none静态方法:
您必须具有子类的实例，并且该方法必须是public方法:

If you want to call a none static method of the child in a parent class:
you have to have an instance of the child class and the method must be a public method:

ChildClass instance = new ChildClass();
instance.MethodName();

或

Or

(new ChildClass()).MethodName();

最好解释一下为什么要这么做.

It''s better If you explain why do you want to do so.
