代理模式：为其它对象提供一个代理，以控制对这个对象的访问。
UML类图
抽象类或者接口：
abstract class Subject
{
public abstract void Request();
}
实现类：
class ReadSubject : Subject
{
public override void Request()
{
Console.WriteLine("真实的请求");
}
}
代理类：
class Proxy:Subject
{
ReadSubject readSubject;
public override void Request()
{
if (readSubject == null)
{
readSubject = new ReadSubject();
}
readSubject.Request();
}
}
客户端：
static void Main(string[] args)
{
Proxy proxy = new Proxy();
proxy.Request();
Console.Read();
}
运行结果：
程序结构：
-----------------------------------------
运算接口：
public interface IMath
{
double Add(double a, double b);
double Sub(double a, double b);
double Mul(double a, double b);
double Div(double a, double b);
}
实现类：
public class Math : IMath
{
public double Add(double a, double b)
{
return a + b;
}
public double Div(double a, double b)
{
return a - b;
}
public double Mul(double a, double b)
{
return a * b;
}
public double Sub(double a, double b)
{
return a / b;
}
}
代理类：
public class MathProxy : MarshalByRefObject, IMath
{
private Math math;
public MathProxy()
{
if (math == null)
{
math = new Math();
}
}
//public MathProxy()
//{
// AppDomain ad = System.AppDomain.CreateDomain("MathDomain", null, null);
// ObjectHandle o = ad.CreateInstance("Proxy_RealWorld", "Math", false, System.Reflection.BindingFlags.CreateInstance, null, null, null, null, null);
// math = (Math)o.Unwrap();
//}
public double Add(double a, double b)
{
return math.Add(a, b);
}
public double Div(double a, double b)
{
return math.Div(a, b);
}
public double Mul(double a, double b)
{
return math.Mul(a, b);
}
public double Sub(double a, double b)
{
return math.Sub(a, b);
}
}
客户端：
static void Main(string[] args)
{
MathProxy p = new MathProxy();
Console.WriteLine(p.Add(4,2));
Console.WriteLine(p.Sub(4, 2));
Console.WriteLine(p.Mul(4, 2));
Console.WriteLine(p.Div(4, 2));
Console.ReadKey();
}
运行结果：
