C# 委托简单示例

C# 委托类似于C函数指针示例使用：

using System;
using System.Reflection;

namespace ConsoleApp7
{
    class Program
    {
        delegate void PrintHello();

        static void print1()
        {
            // 获取当前方法名
            Console.WriteLine(MethodBase.GetCurrentMethod().Name + "  run....");
        }
        static void print2()
        {
            Console.WriteLine(MethodBase.GetCurrentMethod().Name + "  run....");
        }
        static void print3()
        {
            Console.WriteLine(MethodBase.GetCurrentMethod().Name + "  run....");
        }

        static void Main(string[] args)
        {
            PrintHello test_print_del;
            test_print_del = print1;
            test_print_del += print2;
            test_print_del += print3;

            test_print_del();
            Console.WriteLine("=======移除方法=======");
            test_print_del -= print2;
            test_print_del();

            Console.ReadKey();
        }
    }
}

运行结果终端打印：
