我要评论本文实例讲述了c#装饰者模式。分享给大家供大家参考。具体方法如下：
using system;
using system.collections.generic;
using system.linq;
using system.text;
namespace 装饰者
{
class program
{
static void main(string[] args)
{
concretecomponent con = new concretecomponent();
concretedecoratora a = new concretedecoratora();
a.setcomponent(con);
a.operation();
a.addbehavior();
console.writeline("============================");
concretedecoratorb b = new concretedecoratorb();
b.setcomponent(a);
a.addbehavior();
b.operation();
b.addbehavior();
}
public abstract class component
{
public abstract void operation();
}
abstract class decorator : component
{
private component component;
public void setcomponent(component component)
{
this.component = component;
}
public override void operation()
{
if (component != null)
{
component.operation();
}
}
}
class concretedecoratora : decorator
{
public override void operation()
{
base.operation();
}
public void addbehavior()
{
console.writeline("装饰a类的操作！");
}
}
class concretedecoratorb : decorator
{
public override void operation()
{
base.operation();
}
public void addbehavior()
{
console.writeline("装饰b类的操作！");
}
}
public class concretecomponent : component
{
public override void operation()
{
console.writeline("具体对象的操作！");
}
}
}
}
希望本文所述对大家的c#程序设计有所帮助。
