蓝鸥Unity开发基础二——课时26 委托

蓝鸥Unity开发基础二——课时26 委托一、委托
委托是一种特殊的类型，用于引用方法
定义委托需要用delegate关键词
委托可以把方法当做参数来传递
委托可以使用+-运算符合并，解绑委托

using System;

namespace Lesson_26
{

//定义委托——访问修饰符delegate，返回值类型 委托名（参数列表）；

public delegate void Something (string name);
public class Student{

//可以像普通类型一样当做方法参数传递
public void Do(Something something){
//真正调用了方法A——方法回调
something (name);
}
//可以
public Student(string name){
//可以像普通方法一样调用
this.name=name;
}
private string name;

}

public class Teacher{
public void Hungry(){

Student s = new Student ("老王");
//创建委托变量
Something a = new Something (A);
Something b = new Something (B);
Something c = b+a ;

c = c - a;

s.Do (c);

}
public void A(string name){
Console.WriteLine ("Hello,"+name);
}
public void B(string name){

Console.WriteLine (name+"跑十圈");

}

}

class MainClass
{
public static void Main (string[] args)
{
Teacher t = new Teacher ();
t.Hungry ();
}
}
}
