C# 将方法作为参数的方法 -- 委托

源自张子阳的博客

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

namespace Delegate {
//定义委托，它定义了可以代表的方法的类型
public delegate void GreetingDelegate(string name);
class Program {

private static void EnglishGreeting(string name) {
Console.WriteLine("Morning, " + name);
}

private static void ChineseGreeting(string name) {
Console.WriteLine("早上好, " + name);
}

//注意此方法，它接受一个GreetingDelegate类型的方法作为参数
private static void GreetPeople(string name, GreetingDelegate MakeGreeting) {
MakeGreeting(name);
}

static void Main(string[] args) {
GreetPeople("Jimmy Zhang", EnglishGreeting);
GreetPeople("张子阳", ChineseGreeting);
Console.ReadKey();
}
}
}

输出如下：
Morning, Jimmy Zhang
早上好, 张子阳
