Mediator(中介者)模式：
使各个对象不需要显式的相互调用，从而使其耦合松散。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;namespace ds_mediator
{
class Program
{
static void Main(string[] args)
{
ConcreteMediator m = new ConcreteMediator();
ConcreteColleage1 c1 = new ConcreteColleage1(m);
ConcreteColleage2 c2 = new ConcreteColleage2(m);
m.colleage1 = c1;
m.colleage2 = c2;
c1.Send("你好！");
c2.Send("谢谢！");
}
}//抽象同事类
abstract class Colleage
{
protected Mediator mediator;
public Colleage(Mediator mediator)
{
this.mediator = mediator;//得到中介者对象
}
