C#设计模式编程中运用适配器模式结构实战演练

2.对象适配器结构实现

　　Client需要调用Request方法，而Adaptee并没有该方法，为了使Client能够使用Adaptee类，需要提供一个类Adapter。这个类包含了一个Adaptee的实例，将Client与Adaptee衔接起来。

ITarget.cs：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace DesignPatterns.AdapterPattern.Structural.ObjectAdapter
{
 public interface ITarget
 {
  void Request();
 }
}　　

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace DesignPatterns.AdapterPattern.Structural.ObjectAdapter
{
 public class Target : ITarget
 {
  public virtual void Request()
  {
   Console.WriteLine("Called Target Request()");
  }
 }
}　　

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace DesignPatterns.AdapterPattern.Structural.ObjectAdapter
{
 public class Adaptee
 {
  public void SpecificRequest()
  {
   Console.WriteLine("Called SpecificRequest()");
  }
 }
}　

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace DesignPatterns.AdapterPattern.Structural.ObjectAdapter
{
 public class Adapter : Target
 {
  private Adaptee _adaptee = new Adaptee();

  public override void Request()
  {
   _adaptee.SpecificRequest();
  }
 }
}　

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace DesignPatterns.AdapterPattern.Structural.ObjectAdapter
{
 public class Client
 {
  static void Main(string[] args)
  {
   ITarget t = new Adapter();
   t.Request();
  }
 }
}
