前言

在抽象类中封装算法的结构，具体的实现步骤由子类定义，从而达到不改变算法结构的，允许子类重定义方法内容。

代码

public abstract class Teamplate
{public void TeamplateMethod(){Step1();Step2();Step3();}protected abstract void Step1();protected abstract void Step2();protected abstract void Step3();
}
public class ConcreteTemplate : Teamplate
{protected override void Step1(){Console.WriteLine("Step1");}protected override void Step2(){Console.WriteLine("Step2");}protected override void Step3(){Console.WriteLine("Step3");}
}/** 行为型模式：Behavioral Pattern* 模板方法模式：Template Method Pattern*/internal class Program{static void Main(string[] args){Teamplate teamplate = new ConcreteTemplate();teamplate.TeamplateMethod();Console.ReadLine();}}

运行结果
