1、首先定义一个接口ICalculate

(1)引入System.ServiceModel程序集

(2)公开接口，使用ServiceContract特性定义服务契约（标注interface），OpeattionContract特性标注Method

using System.ServiceModel;

namespace CalculateImplement

{

    [ServiceContract]

    public interface ICalculate

    {

        [OperationContract]

        double Add(double x, double y);

    }

}

2、接口的实现

namespace CalculateImplement

{

    public class Calculate : ICalculate

    {

        public double Add(double x, double y)

        {

            return x + y;

        }

    }

}

3、Host管理服务

<?xml version="1.0" encoding="utf-8" ?>

<configuration>

    <startup>

        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />

    </startup>

    <!--WCF Setting-->

  <system.serviceModel>

    <services>

      <service name="CalculateImplement.Calculate" behaviorConfiguration="serviceBehavior">

        <host>

          <baseAddresses>

            <add baseAddress="http://localhost:9001"/>

          </baseAddresses>

        </host>

        <endpoint name="CalculateImplementEndPoint"

                  address="CalculateImplement"

                  binding="basicHttpBinding"

                  contract="CalculateImplement.ICalculate"/>

        <endpoint name="mex"

                  binding ="mexHttpBinding"

                  contract="IMetadataExchange"

                  address="mex"/>

      </service>

    </services>

    <behaviors>

      <serviceBehaviors>

        <behavior name="serviceBehavior">

          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="false"/>

          <serviceDebug includeExceptionDetailInFaults="false"/>

        </behavior>

      </serviceBehaviors>

    </behaviors>

  </system.serviceModel>

</configuration>

using System;

using System.ServiceModel;

using CalculateImplement;

namespace HostService

{

    class Program

    {

        static void Main(string[] args)

        {

            ServiceHost host = new ServiceHost(typeof(Calculate));

            try

            {

                host.Open();

                Console.WriteLine("Service is open......");

                Console.ReadLine();

                host.Close();

            }

            catch (Exception et)

            {

                throw et;

            }

        }

    }

}

4、开启Host，在Client端添加Service，修改命名空间

Client代码：

using System;

namespace Client

{

    class Program

    {

        static void Main(string[] args)

        {

            CalculateService.CalculateClient calculate = new CalculateService.CalculateClient();

            Console.WriteLine("SOA Demo");

            Console.Write("Please enter the first number:");

            double num1 = Convert.ToDouble(Console.ReadLine());

            Console.Write("Please enter the second number:");

            double num2 = Convert.ToDouble(Console.ReadLine());

            double result = calculate.Add(num1, num2);

            Console.WriteLine("Add result:" + result);

            Console.ReadLine();

        }

    }

}
