c# - 这种继承设计模式的名称是什么？

Question

您有一个调用 protected 虚方法的公共(public)密封方法，而不是公共(public)虚方法。像这样:

public class Test {

    public void DoStuff(){
        // Do stuff here...
        ProtectedDoStuff();
        // Do more stuff...
    }

    protected virtual void ProtectedDoStuff(){
        // Do stuff...
    }
}

代替:

public class Test {

    public virtual void DoStuff(){
        // Do stuff here...
        // Do a lot of stuff...
        // Do more stuff...
    }
}

public class Test2 : Test {

    public override void DoStuff(){
        // Do same stuff as base
        // Do different stuff
        // Do more stuff just like base
    }
}

这避免了在所有时间都需要的情况下必须重新实现公共(public)方法中的所有功能。我知道这已经在 stackoverflow 上被问到了，但我找不到问题。

这是模板方法模式。来自 Wikipedia :

The template method pattern is a behavioral design pattern that defines the program skeleton of an algorithm in a method, called template method, which defers some steps to subclasses. It lets one redefine certain steps of an algorithm without changing the algorithm's structure.
