类库 System.ServiceModle

WCF类库

契约IUser1，实现User1

[ServiceContract]

    public interface IUser1

    {

        [OperationContract]

        string GetUser1Name(string name);

    }

    public class User1 : IUser1

    {

        public string GetUser1Name(string name)

        {

            return "我是usre1" + name;

        }

    }

契约IUser2 ，实现User2

    [ServiceContract]

    public interface IUser2

    {

        [OperationContract]

        string GetUser1Name(string name);

    }

    public class User2 : IUser2

    {

        public string GetUser1Name(string name)

        {

            return "我是user2" + name;

        }

    }

契约IUnity1和IUnity2，实现Unity（一个实现继承了两个契约，主意看一下配置文件如何配置）

    [ServiceContract]

    public interface IUnity1

    {

        [OperationContract]

        int GetUnityCount();

    }

    [ServiceContract]

    public interface IUnity2

    {

        [OperationContract]

        string GetUnityString();

    }

    public class Unity : IUnity1, IUnity2

    {

        public int GetUnityCount()

        {

            return ;

        }

        public string GetUnityString()

        {

            return "Unity";

        }

    }

宿主

        static void Main(string[] args)

        {

            ServiceHost sh1 = new ServiceHost(typeof(WcfLib.User1));

            sh1.Open();

            Console.WriteLine("服务1开启");

            ServiceHost sh2 = new ServiceHost(typeof(WcfLib.User2));

            sh2.Open();

            Console.WriteLine("服务2开启");

            ServiceHost sh3 = new ServiceHost(typeof(WcfLib.Unity.Unity));

            sh3.Open();

            Console.WriteLine("服务3开启");

            Console.ReadKey();

        }

　　服务配置文件

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

<configuration>

  <startup>

    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" />

  </startup>

  <system.serviceModel>

    <services>

      <!--name="命名空间名称.实现类名称"-->

      <service name="WcfLib.User1"  behaviorConfiguration="mexBehaviour">

        <endpoint address="MyServices1" binding="basicHttpBinding" contract="WcfLib.IUser1">

        </endpoint>

        <host>

          <baseAddresses>

            <add baseAddress="http://localhost:9999/"/>

          </baseAddresses>

        </host>

      </service>

      <service name="WcfLib.User2" behaviorConfiguration="mexBehaviour">

        <host>

          <baseAddresses>

            <add baseAddress="http://localhost:6666/"/>

          </baseAddresses>

        </host>

        <endpoint address="MyServices2" binding="basicHttpBinding" contract="WcfLib.IUser2"></endpoint>

      </service>

      <service name="WcfLib.Unity.Unity" behaviorConfiguration="mexBehaviour">

        <host>

          <baseAddresses>

            <add baseAddress="http://localhost:7777/"/>

            <add baseAddress="net.tcp://localhost:7776/"/>

          </baseAddresses>

        </host>

        <endpoint address="MyServices3" binding="basicHttpBinding" contract="WcfLib.Unity.IUnity1" ></endpoint>

        <!--错误:找不到具有绑定 NetTcpBinding 的终结点的与方案 net.tcp 匹配的基址。注 册的基址方案是 [http]。   解决:TCP通讯 地址必须是TCP的（TCP不能宿主在IIS上）   net.tcp://localhost:7776/-->

        <endpoint address="MyServices4" binding="netTcpBinding" contract="WcfLib.Unity.IUnity2"></endpoint>

      </service>

    </services>

    <behaviors>

      <serviceBehaviors>

        <behavior name="mexBehaviour">

          <!--设置未false被人不能发现，一般当客户端已经加载好服务代理就可以设置为false了。配置修改，服务要重启，才能生效-->

          <serviceMetadata httpGetEnabled="true" />

        </behavior>

        <behavior>

        </behavior>

      </serviceBehaviors>

    </behaviors>

  </system.serviceModel>

</configuration>

客户端

右键添加服务

配置文件自动生成

        static void Main(string[] args)

        {

            WCFServiceUser1.User1Client cli1 = new WCFServiceUser1.User1Client();

            WCFServiceUser2.User2Client cli2 = new WCFServiceUser2.User2Client();

            WCFServiceUnity.Unity1Client cli3 = new WCFServiceUnity.Unity1Client();

            WCFServiceUnity.Unity2Client cli4 = new WCFServiceUnity.Unity2Client();

            Console.WriteLine(cli1.GetUser1Name("name1"));

            Console.WriteLine(cli2.GetUser1Name("name2"));

            Console.WriteLine(cli3.GetUnityCount());

            Console.WriteLine(cli4.GetUnityString());

        }

WCF 调用服务标准写法

static void Main(string[] args)

        {

            //不适用using，原因using在网络中断时，wcf不能关闭。websevice可以是用using释放，websevice标准写法是用using

            CustomService.UserServiceSoapClient ucli = null;

            try

            {

                ucli = new CustomService.UserServiceSoapClient();

                ucli.GetStr("");

                //手动释放，

                ucli.Close();

            }

            catch (Exception)

            {

                if (ucli != null)

                {

                    ucli.Abort();

                }

            }

        }
