C# 继承

class ClassF  //基类
        {
            //公有字段
            public string name = "张三";
            public string age;
            //公有属性
            public string Age
            {
                get { return age; }
                set { age = value; }
            }
            //虚拟方法
            public virtual double Income(double time)
            {
                double income = time * 100.0 + 2000.0;
                return income;
            }
        }
        class ClassS : ClassF  //派生类
        {
            //重写虚拟方法
            public override double Income(double time)
            {
                double income = time * 100.0 + 3000.0;
                return income;
            }
            static void Main(string[] args)
            {
                ClassS cs = new ClassS();
                Console.Write("姓名:");
                Console.WriteLine(cs.name); //继承了公有字段
                Console.Write("请输入工龄:");
                cs.Age = Console.ReadLine(); //继承了公有属性
                Console.Write("工资:");
                Console.WriteLine(cs.Income(Convert.ToDouble(cs.Age)).ToString()); //继承了虚拟方法
                Console.ReadKey();
            }
        }

 

运行结果:

姓名:张三

请输入工龄:20

工资:5000
