WCF第一例

ABC: Address,Binding(BasicHttpBinding/WSHttpBinding/NetTcpBinding etc.),Contract

1.添加一个WCF服务库项目

//IService1.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;

namespace HelloIndigoWCF
{
    // 注意: 如果更改此处的接口名称“IService1”,也必须更新 App.config 中对“IService1”的引用。
    [ServiceContract]
    public interface IService1
    {
        [OperationContract]
        string GetData(int value);

        [OperationContract]
        CompositeType GetDataUsingDataContract(CompositeType composite);

        // 任务: 在此处添加服务操作
    }

    // 使用下面示例中说明的数据协定将复合类型添加到服务操作
    [DataContract]
    public class CompositeType
    {
        bool boolValue = true;
        string stringValue = "Hello ";

        [DataMember]
        public bool BoolValue
        {
            get { return boolValue; }
            set { boolValue = value; }
        }

        [DataMember]
        public string StringValue
        {
            get { return stringValue; }
            set { stringValue = value; }
        }
    }
}

//Service1.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;

namespace HelloIndigoWCF
{
    // 注意: 如果更改此处的类名“IService1”,也必须更新 App.config 中对“IService1”的引用。
    public class Service1 : IService1
    {
        public string GetData(int value)
        {
            return string.Format("You entered: {0}", value);
        }

        public CompositeType GetDataUsingDataContract(CompositeType composite)
        {
            if (composite.BoolValue)
            {
                composite.StringValue += "Suffix";
            }
            return composite;
        }
    }
}

App.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.web>
    <compilation debug="true" />
  </system.web>
  <!-- 部署服务库项目时,必须将配置文件的内容添加到 
  主机的 app.config 文件中。System.Configuration 不支持库的配置文件。-->
  <system.serviceModel>
    <services>
      <service name="HelloIndigoWCF.Service1" behaviorConfiguration="HelloIndigoWCF.Service1Behavior">
        <host>
          <baseAddresses>
            <add baseAddress = "http://localhost:65534/Design_Time_Addresses/HelloIndigoWCF/Service1/" />
          </baseAddresses>
        </host>
        <!-- Service Endpoints -->
        <!-- 除非完全限定,否则地址将与上面提供的基址相关 -->
        <endpoint address ="" binding="wsHttpBinding" contract="HelloIndigoWCF.IService1">
          <!-- 
              部署时,应删除或替换下列标识元素,以反映
              在其下运行部署服务的标识。删除之后,WCF 将
              自动推导相应标识。
          -->
          <identity>
            <dns value="localhost"/>
          </identity>
        </endpoint>
        <!-- Metadata Endpoints -->
        <!-- 元数据交换终结点由服务用于向客户端做自我描述。--> 
        <!-- 此终结点不使用安全绑定,应在部署前确保其安全或将其删除-->
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="HelloIndigoWCF.Service1Behavior">
          <!-- 为避免泄漏元数据信息,
          请在部署前将以下值设置为 false 并删除上面的元数据终结点  -->
          <serviceMetadata httpGetEnabled="True"/>
          <!-- 要接收故障异常详细信息以进行调试, 
          请将下值设置为 true。在部署前 
            设置为 false 以避免泄漏异常信息-->
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

2.Host项目

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;

namespace Host
{
    class Program
    {
        internal static ServiceHost myServiceHost = null;
        internal static void StartService()
        {
            myServiceHost = new ServiceHost(typeof(HelloIndigoWCF.Service1));
            myServiceHost.AddServiceEndpoint(typeof(HelloIndigoWCF.IService1), new WSHttpBinding(), "http://localhost:3391/abc");
            myServiceHost.Open();
        }
        internal static void StopService()
        {
            if (myServiceHost.State != CommunicationState.Closed)
                myServiceHost.Close();
        }

        static void Main(string[] args)
        {
            //using (ServiceHost host = new ServiceHost(typeof(HelloEmployee)))
            //{
            //    host.AddServiceEndpoint(typeof(IHelloEmployee), new WSHttpBinding(), "http://localhost:9002/MyEmployee");
            //    host.Open();
            //    Console.ReadLine();
            //}
            StartService();
            Console.WriteLine("the server is running ...");
            Console.ReadLine();
            StopService();

        }
    }
}

3.ClientApp

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using System.ServiceModel;

namespace Client
{
    class Program
    {
        static void Main(string[] args)
        {
            HelloIndigoWCF.IService1 proxy = ChannelFactory<HelloIndigoWCF.IService1>.CreateChannel(new WSHttpBinding()
                , new EndpointAddress("http://localhost:3391/abc"));

            //HelloIndigoWCF.IService1 proxy = ChannelFactory<HelloIndigoWCF.IService1>.CreateChannel(new NetTcpBinding(), new EndpointAddress("net.tcp://localhost:9000/HelloIndigo"));
            //localhost.HelloIndigoServiceClient proxy = new Client.localhost.HelloIndigoServiceClient();

            string s = proxy.GetData(1024);

            Console.WriteLine(s);
            Console.ReadLine();

        }
    }
}
