【5】.net WCF 简单实例

1.创建WCF项目

2.系统自动生成IWcfService

    // 注意: 使用“重构”菜单上的“重命名”命令，可以同时更改代码和配置文件中的接口名“IService1”。
    [ServiceContract]
    public interface IWcfService
    {

        [OperationContract]
        string GetData(int value);

        [OperationContract]
        CompositeType GetDataUsingDataContract(CompositeType composite);

        // TODO: 在此添加您的服务操作
    }


    // 使用下面示例中说明的数据约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; }
        }
    }

（1）服务契约：ServiceContract（服务）和OperationContract  （方法）

（2）数据契约：DataContract（类）和DataMember（属性） 用于类和结构上

（3）消息契约：MessageContract 用于soap消息

3.WCF服务类

    public class WcfService : IWcfService
    {
        public string GetData(int value)
        {
            return string.Format("You entered: {0}", value);
        }

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

4.服务配置文件

  <system.serviceModel>
    <!--配置绑定节点Start-->
    <bindings>
      <basicHttpBinding>
        <binding name="basicHttpBinding0" maxReceivedMessageSize="2147483647">
          <readerQuotas maxStringContentLength="2147483647"/>
          <security mode="None" />
        </binding>
      </basicHttpBinding>
      <netTcpBinding>
        <binding name="netTcpBinding0" maxReceivedMessageSize="2147483647">
          <readerQuotas maxStringContentLength="2147483647"/>
          <security mode="None" />
        </binding>
      </netTcpBinding>
      <wsHttpBinding></wsHttpBinding>
    </bindings>
    <!--配置绑定节点End-->
    
    <!--配置服务节点Start-->
    <services>
      <!--配置某一服务，在这里可以指定服务名称-->
      <service name="WcfServiceTest.WcfService">
        <endpoint address="aaa" binding="basicHttpBinding" bindingConfiguration="basicHttpBinding0"
          name="BasicHttpBinding_WcfService" contract="WcfServiceTest.IWcfService">
          <identity>
            <dns value="localhost"/>
          </identity>
        </endpoint>
        <endpoint address="" binding="netTcpBinding" bindingConfiguration="netTcpBinding0"
          name="NetTcpBinding_WcfService" contract="WcfServiceTest.IWcfService">
          <identity>
            <dns value="localhost"/>
          </identity>
        </endpoint>
      </service>
    </services>
    <!--配置服务节点End-->

    <behaviors>
      <serviceBehaviors>
        <behavior>
          <!-- 为避免泄漏元数据信息，请在部署前将以下值设置为 false -->
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
          <!-- 要接收故障异常详细信息以进行调试，请将以下值设置为 true。在部署前设置为 false 以避免泄漏异常信息 -->
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <protocolMapping>
        <add binding="basicHttpsBinding" scheme="https" />
    </protocolMapping>    
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
  </system.serviceModel>

5.iis部署WCF服务

6.添加客户端项目并添加服务引用

7.Main程序中添加wcf服务并调用方法

    class Program
    {
        static void Main(string[] args)
        {
            var client = new WcfService.WcfServiceClient();
            try
            {
                var str = client.GetData(2046);
                Console.WriteLine(string.Format("内容:{0}", str));
                client.Close();
            }
            catch (Exception ex)
            {
                Console.WriteLine("出现异常！");
                client.Abort();
            }
            Console.ReadLine();
        }
    }

8.客户端配置文件

    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="BasicHttpBinding_WcfService" />
            </basicHttpBinding>
            <netTcpBinding>
                <binding name="NetTcpBinding_WcfService">
                    <security mode="None" />
                </binding>
            </netTcpBinding>
        </bindings>
        <client>
            <!--<endpoint address="http://localhost/WcfServiceTest/WcfService.svc"
                binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_WcfService"
                contract="WcfService.IWcfService" name="BasicHttpBinding_WcfService" />-->
            <endpoint address="net.tcp://localhost/WcfServiceTest/WcfService.svc"
                binding="netTcpBinding" bindingConfiguration="NetTcpBinding_WcfService"
                contract="WcfService.IWcfService" name="NetTcpBinding_WcfService">
                <identity>
                    <dns value="localhost" />
                </identity>
            </endpoint>
        </client>
    </system.serviceModel>
