一步一步构建服务并用Windows服务承载，以及调用

声明：试验环境，不与实际开发，勿混淆。（否则，责任自负）

第一步，构建服务。

新建 “WCF服务库项目”

IBasicMath.cs代码如下（别忘了添加引用了！）

using System;
using System.Runtime.Serialization;
using System.ServiceModel;

namespace MathServiceLibrary
{
    [ServiceContract(Namespace="www.Intertech.com")]
    public interface IBasicMath
    {
        [OperationContract]
        int Add(int x, int y);
    }
}

MathService.cs代码如下

using System;
using System.Runtime.Serialization;
using System.ServiceModel;

namespace MathServiceLibrary
{
    public class MathService : IBasicMath
    {

        public int Add(int x, int y)
        {
            return x + y;
        }
    }
}

App.config代码如下（它应该会自动创建的...）

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

  <appSettings>
    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
  </appSettings>
  <system.web>
    <compilation debug="true" />
  </system.web>
  <system.serviceModel>
    <services>
      <service name="MathServiceLibrary.MathService">
        <endpoint address="" binding="wsHttpBinding" bindingConfiguration=""
          contract="MathServiceLibrary.IBasicMath">
          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8733/Design_Time_Addresses/MathServiceLibrary/Service1/" />
          </baseAddresses>
        </host>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpGetEnabled="True" httpsGetEnabled="True"/>
          <serviceDebug includeExceptionDetailInFaults="False" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>

</configuration>

然后，生成。

第二步，使用 Windows 承载 WCF 服务

 新建 “Windows服务” 项目

MathWinService 代码如下

using System;
using System.ServiceProcess;
using MathServiceLibrary;
using System.ServiceModel;

namespace MathWindowsServiceHost
{
    public partial class MathWinService : ServiceBase
    {
        private ServiceHost myHost;
        public MathWinService()
        {
            InitializeComponent();
        }

        protected override void OnStart(string[] args)
        {
            //确保安全
            if (myHost != null) {
                myHost.Close();
                myHost = null;
            }
            //创建宿主
            myHost = new ServiceHost(typeof(MathService));
            //ABC
            Uri address = new Uri("http://localhost:8080/MathServiceLibrary");
            WSHttpBinding binding = new WSHttpBinding();
            Type contract = typeof(IBasicMath);
            //增加端点
            myHost.AddServiceEndpoint(contract, binding, address);
            //打开宿主
            myHost.Open();
        }

        protected override void OnStop()
        {
            //关闭宿主
            if (myHost != null)
                myHost.Close();
        }
    }
}

App.config 代码如下

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
    </startup>
  <system.serviceModel>
    <services>
      <service name="MathServiceLibrary.MathService"
               behaviorConfiguration ="MathServiceMEXBehavior">
        <endpoint address="mex"
                  binding="mexHttpBinding"
                  contract="IMetadataExchange"/>
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8080/MathService"/>
          </baseAddresses>
        </host>
      </service>
    </services>

    <behaviors>
      <serviceBehaviors>
        <behavior name="MathServiceMEXBehavior">
          <serviceMetadata httpGetEnabled="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

然后打开设计器，右键 “添加安装程序”

此时，窗体上应该会出现两个组件

第一个表示windows服务的类型，比如 Account 属性，指明了运行此服务的账户类型。 此处改为 “LocalSystem”

第二个表示此服务的类型，比如 ServiceName 属性，指明了 “服务名”， Description 指明了 “服务介绍”。生成它

最后，安装服务

找到 MathWindowsServiceHost.exe

使用开发人员命令提示： installutil MathWindowsServiceHost.exe

如果安装成功，服务里面就可以看到了

第三步，消费此服务

新建 “MathClient” 项目

添加服务引用

Program.cs代码如下

using System;
using MathClient.ServiceReference;

namespace MathClient
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("******* It's a new Day ! ********");
            using (BasicMathClient proxy = new BasicMathClient()) {
                proxy.Open();
                Console.WriteLine("2 + 3 = {0}",proxy.Add(2, 3));
            }
            Console.ReadLine();
        }
    }
}

如果你的服务已经运行的话，那么启动它吧！
