WCF简单实例[改进版]

一 实例结构

1）solution如下：

 

2）dependency如下：

 

 

*  Contracts 其实就是interface，用来实现service和client的松耦合；

*  Services 是真正的对contracts实现；

*  Hosting 用来宿主 services，是其能够被client访问；

*  client 用来访问wcf service；

 

二 contracts

ICalculator.cs文件如下：

  using  System.ServiceModel;

  namespace  Artech.WcfServices.Contracts
 {
     [ServiceContract(Name = " CalculatorService " , Namespace = " http://www.artech.com/ " )]
      public   interface  ICalculator
    {

       [OperationContract]
        double  Add( double  x,  double  y);

        [OperationContract]
         double  Subtract( double  x,  double  y); 

        [OperationContract]
         double  Multiply( double  x,  double  y); 

        [OperationContract]
         double  Divide( double  x,  double  y);      
    } 
}

三 services

CalculatorService.cs文件如下：

using  Artech.WcfServices.Contracts;

namespace  Artech.WcfServices.Services
{

     public   class  CalculatorService : ICalculator
    {
         public   double  Add( double  x,  double  y)
        {
             return  x  +  y;
        }
         public   double  Subtract( double  x,  double  y)
        {
             return  x  -  y;
        }
         public   double  Multiply( double  x,  double  y)
        {
             return  x  *  y;
        }
         public   double  Divide( double  x,  double  y)
        {
             return  x  /  y;
        }
    }
}

 

四 hosting

app.config文件如下：

<? xml version="1.0" encoding="utf-8"  ?>
< configuration >
   < system.serviceModel >
     < behaviors >
       < serviceBehaviors >
         < behavior  name ="metadataBehavior" >
           < serviceMetadata  httpGetEnabled ="true"  httpGetUrl ="http://localhost:8888/calculatorservice/metadata"   />
         </ behavior >
       </ serviceBehaviors >
     </ behaviors >
     < services >
       < service  behaviorConfiguration ="metadataBehavior"  name ="Artech.WcfServices.Services.CalculatorService" >
         < endpoint  address ="http://localhost:8888/calculatorservice"  binding ="wsHttpBinding"   contract ="Artech.WcfServices.Contracts.ICalculator"   />
       </ service >
     </ services >
   </ system.serviceModel >
</ configuration >

Hosting.cs文件如下：

using  System;
using  System.ServiceModel;

using  Artech.WcfServices.Contracts;
using  Artech.WcfServices.Services;

namespace  Artech.WcfServices.Hosting
{
    class  Program
   {

        static   void  Main( string [] args)
       {
            using  (ServiceHost host  =   new  ServiceHost( typeof (CalculatorService)))
           {                
               host.Opened  +=   delegate
                {
                    Console.WriteLine( " CalculaorService已经启动，按任意键终止服务！ " );
                };

                host.Open();
                Console.Read();
            }
        }
    }
}

 

五 client

app.config文件如下：

<? xml version="1.0" encoding="utf-8"  ?>
< configuration >
< system.serviceModel >
< client >
< endpoint  address ="http://localhost:8888/calculatorservice"  binding ="wsHttpBinding"
contract ="Artech.WcfServices.Contracts.ICalculator"  name ="calculatorservice"   />
</ client >
</ system.serviceModel >
</ configuration >

client.cs文件如下：

using  System;
using  System.ServiceModel;

using  Artech.WcfServices.Contracts;

namespace  Artech.WcfServices.Client
{
    class  Program
   {
        static   void  Main( string [] args)
       {
            using  (ChannelFactory < ICalculator >  channelFactory  =   new  ChannelFactory < ICalculator > ( " calculatorservice " ))
            {
                ICalculator proxy  =  channelFactory.CreateChannel();
                 using  (proxy  as  IDisposable)
                {
                    Console.WriteLine( " x + y = {2} when x = {0} and y = {1} " ,  1 ,  2 , proxy.Add( 1 ,  2 ));
                    Console.WriteLine( " x - y = {2} when x = {0} and y = {1} " ,  1 ,  2 , proxy.Subtract( 1 ,  2 ));
                    Console.WriteLine( " x * y = {2} when x = {0} and y = {1} " ,  1 ,  2 , proxy.Multiply( 1 ,  2 ));
                    Console.WriteLine( " x / y = {2} when x = {0} and y = {1} " ,  1 ,  2 , proxy.Divide( 1 ,  2 ));
                }
            }
           Console.ReadLine();
        }
    }
}
