我要评论本文实例讲述了c#职责链模式。分享给大家供大家参考。具体如下：
concretehandler1.cs如下：
using system;
using system.collections.generic;
using system.linq;
using system.text;
namespace consoleapplication1
{
public class concretehandler1:handler
{
public override void handrequest(int request)
{
if(request>0&&request<10)
{
console.writeline("{0} 处理请求 {1}",this.gettype().name,request);
}
else if(successor!=null)
{
successor.handrequest(request);
}
}
}
}
concretehandler2.cs如下：
using system;
using system.collections.generic;
using system.linq;
using system.text;
namespace consoleapplication1
{
public class concretehandler2:handler
{
public override void handrequest(int request)
{
if (request > 10 && request < 20)
{
console.writeline("{0} 处理请求 {1}", this.gettype().name, request);
}
else if (successor != null)
{
successor.handrequest(request);
}
}
}
}
concretehandler3.cs如下：
using system;
using system.collections.generic;
using system.linq;
using system.text;
namespace consoleapplication1
{
public class concretehandler3:handler
{
public override void handrequest(int request)
{
if (request > 20 && request < 30)
{
console.writeline("{0} 处理请求 {1}", this.gettype().name, request);
}
else if (successor != null)
{
successor.handrequest(request);
}
}
}
}
handler.cs如下：
using system;
using system.collections.generic;
using system.linq;
using system.text;
namespace consoleapplication1
{
public abstract class handler
{
protected handler successor;
public void setsuccessor(handler successor)
{
this.successor = successor;
}
public abstract void handrequest(int request);
}
}
program.cs如下：
using system;
using system.collections.generic;
using system.linq;
using system.text;
namespace consoleapplication1
{
class program
{
static void main(string[] args)
{
handler h1 = new concretehandler1();
handler h2 = new concretehandler2();
handler h3 = new concretehandler3();
h1.setsuccessor(h2);
h2.setsuccessor(h3);
int[] requests = {2,5,14,22,18,3,27,20};
foreach(int request in requests)
{
h1.handrequest(request);
}
console.readkey();
}
}
}
希望本文所述对大家的c#程序设计有所帮助。
