1、首先定義一個接口ICalculate

(1)引入System.ServiceModel程序集

(2)公開接口，使用ServiceContract特性定義服務契約（標注interface），OpeattionContract特性標注Method

using System.ServiceModel;namespace CalculateImplement{    [ServiceContract]    public interface ICalculate    {        [OperationContract]        double Add(double x, double y);    }}

2、接口的實現

namespace CalculateImplement{    public class Calculate : ICalculate    {        public double Add(double x, double y)        {            return x + y;        }    }}

3、Host管理服務

<?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、開啟Host，在Client端添加Service，修改命名空間

Client代碼：

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();        }    }}
