[C#] 委托与匿名方法

using System;

 

namespace 匿名函数

{

    class Program

    {

        delegate void TestDelegate(string s);

 

        static void M(string s)

        {

            Console.WriteLine("A参数为：{0}", s);

        }

 

        static void Main(string[] args)

        {

            //1. 委托的基本写法，及调用

            TestDelegate testDeleA = new TestDelegate(M);//通过委托的实例化将之与方法绑定

            testDeleA("hahahah");

 

            //2. 使用匿名表达式构造委托调用方法

            //C#2.0 Anonymous Method，其结构为：delegate+(各个参数)+{函数体}

            TestDelegate testDeleB = delegate (string s) { Console.WriteLine("B参数为：{0}", s); };//直接通过delegate声明将之与函数体绑定

            testDeleB("hehehehe");

            //C#3.0, 引入lamda表达法，Lambda Expression

            TestDelegate testDeleC = (x) => { Console.WriteLine("C参数为：{0}", x); };

            testDeleC("hohoho");

 

            Console.ReadKey();

        }

 

    }
