c# 02.1 继承 子类给父类传参

补充一点子类调用父类构造器

子类

using System;
using System.Collections;
using System.Collections.Generic;
using System.Text;

namespace ConsoleApp1 
{
    /// <summary>
    /// 胡萝卜类
    /// </summary>
     class Carrot : Vegetables
    {
        public static void Main(string[] args)
        {
            Carrot c = new Carrot("aaa");
        }

        //public Carrot() { }

        public Carrot(string var) : base(var) { }//将传给子类构造器的参数传给父类构造器
       
    }
}

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 Vegetables(string var) {
            this.Vitamin = var;
            Console.WriteLine("调到我这儿来了并且传的参数是：{0}",var);
        }

        //public Vegetables() { }
    }
}

结果：
