C#设计模式学习小结之六 外观模式

将子系统灵活组合封装时可用

using System;

namespace 外观模式
{
class Program
{
static void Main(string[] args)
{
Facade f = new Facade();
f.MethodOne();
f.MethodTwo();
Console.Read();
}
}

class SubSystemOne
{
public void MethodOne()
{
Console.WriteLine("子系统1方法1");
}

public void MethodTwo()
{
Console.WriteLine("子系统1方法2");
}
}

class SubSystemTwo
{
public void MethodOne()
{
Console.WriteLine("子系统2方法1");
}

public void MethodTwo()
{
Console.WriteLine("子系统2方法2");
}
}

class Facade //外观类
{
SubSystemOne one;
SubSystemTwo two;

public Facade()
{
one = new SubSystemOne();
two = new SubSystemTwo();
}

public void MethodOne()
{
Console.WriteLine("父系统方法1");
one.MethodOne();
two.MethodTwo();
}

public void MethodTwo()
{
Console.WriteLine("父系统方法2");
one.MethodTwo();
two.MethodOne();
}
}

}
