string方法的一些函数作用
2.继承演示
-子类
using System;
using System.Collections.Generic;
using System.Text;
namespace ConsoleApp1
{
/// <summary>
/// 胡萝卜类:继承与蔬菜类。在这里继承是这样写的“:”
/// </summary>
class Carrot : Vegetables
{
public static void Main(string[] args) {
Carrot carrot = new Carrot();
carrot.effect();//调用的父类的方法
carrot.rhizome();//调的子类的方法
carrot.Vitamin = "abcdefghijklmnopqrstuvwxyz";//给父类赋值
}
/// <summary>
/// 隐藏基类方法
/// </summary>
public new void rhizome()
{
Console.WriteLine("细小根茎类植物");
}
}
}
-父类
using System;
using System.Collections.Generic;
using System.Text;
namespace ConsoleApp1
{
/// <summary>
/// 蔬菜类
/// </summary>
class Vegetables
{
/// <summary>
/// 维生素
/// </summary>
private string _vitamin;
public string Vitamin { get => _vitamin; set => _vitamin = value; }
public void effect() {
Console.WriteLine("多吃有益健康");
}
public void rhizome() {
Console.WriteLine("根茎类植物");
}
}
}
