使用SOA来实现两个数字的相加，不包含验证，仅供练习使用。

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();
        }
    }
}
