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();
        }
    }
}
