C# 回调与 javascritp 回调 比较

C#:

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 welcomeDelegate(string name);
        class Program {

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

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

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

           static void Main(string[] args) {
               GreetPeople("Jimm", EnglishWelcome);
               GreetPeople("吉姆", ChineseWelcome);
               Console.ReadKey();
           }
        }
    }

ＪＳ：

function ChinseWelcome(var name){ 
alert("你好"+name); 
} 

function EnglishWelcome(var name){ 
alert("hello"+name); 
} 

function WelcomePeople(var name,WelcomeMethod) 
{    
    WelcomeMethod(name); 
} 

function test() 
{ 
   WelcomePeople("Jimm",ChinseWelcome); 
   WelcomePeople("吉姆",EnglishWelcome);  
}

js 的回调与C#有异曲同工之妙,C#的代理功能更强大，增加了链式结构和轮播功能。
