抽象方法演练

using System;


abstract class Employee //定义抽象类




...{


protected string _name;//只被本类或派生类访问


protected Employee()//默认构造函数




...{




}


protected Employee(string name)//带一个参数的构造函数




...{


_name = name;


}


abstract public void strartWork();//抽象方法






}


class Manager : Employee




...{


public Manager(string name): base(name)//指定构造函数




...{ }


public override void strartWork()//重写基类虚方法




...{




Console.WriteLine(_name+"给员工下达任务");


}




}


class xs : Employee




...{


public xs(string name):base(name)//指定构造函数




...{ }


public override void strartWork()




...{




Console.WriteLine(_name + "销售产品");


}




}


class ms : Employee




...{


public ms(string name) : base(name)//指定构造函数




...{ }


public override void strartWork()




...{




Console.WriteLine(_name + "经理助理");


}




}




class kj : Employee




...{


public kj(string name) : base(name)//指定构造函数




...{ }


public override void strartWork()




...{




Console.WriteLine(_name + "财务核算");


}




}




class Test




...{


static void Main()




...{


Employee [] emp =new Employee[4];//并没有实例化Employee抽象类,而是建立了一个Employee类型的数组,new的是数组


emp[0]=new Manager("张三");


emp[1]=new xs("李四");


emp[2]=new ms("王五");


emp[3]=new kj("赵六");


Console.WriteLine("上午8点开始工作:");


foreach(Employee e in emp)




...{


e.strartWork();


}




}


}
