委托，匿名函数

委托

• 类似于python反射，将函数名当参数使用

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
using System.Threading.Tasks;


namespace delegate_test
{
    class Program
    {
        public delegate void DeleSayHi(string str_name);
        static void Main(string[] args)
        {

            SayEnglish("张三");
            Test("彭菊菊", SayChinese);
            Test("fxx", SayEnglish);
            Console.ReadKey();
        }

        public static void Test(string str_name, DeleSayHi del)
        {
            del(str_name);
        }

        public static void SayChinese(string str_name)
        {
            Console.WriteLine($"我是{str_name}");

        }
        public static void SayEnglish(string str_name)
        {
            Console.WriteLine($"My name is {str_name}");
        }
    }
}
