WCF服务入门

1.新建类库Contract，类库内创建类ICalu.此项目为服务契约，为客户端访问提供接口。

[ServiceContract]
    public interface ICalu
    {
        [OperationContract]
 　　　　[FaultContract(typeof(WCFException))]
        string DoWork(int i);
    }
也可以定义一些数据契约
如：

 [DataContract]
    public class WCFException
    {
        private string _operation;
        private string _errorMessage;


        /// <summary>
        /// 自定义WCF错误包的构造函数
        /// </summary>
        /// <param name="operation"></param>
        /// <param name="errorMessage"></param>
        public WCFException(string operation, string errorMessage)
        {
            this.Operation = operation;
            this.ErrorMessage = errorMessage;
        }

        /// <summary>
        /// 产生错误的操作信息
        /// </summary>
        [DataMember]
        public string Operation
        {
            get { return _operation; }
            set { _operation = value; }
        }

        /// <summary>
        /// 产生的异常信息
        /// </summary>
        [DataMember]
        public string ErrorMessage
        {
            get { return _errorMessage; }
            set { _errorMessage = value; }
        }
    }

 

2.新建类库项目Services。实现上面的接口。

 public class Calu : ICalu
    {
        public void DoWork()
        {
        }
    }

3.建立一个空的web项目Host。承载WCF服务。

<%@ ServiceHost Language="C#" Debug="true" Service="Services.Calu" %>

新建名为Calu的WCF服务，删除Calu.svc.cs文件和ICalu.cs。打开Calu.svc，删除后面的codebihind，修改 Service="Services.Calu" 为服务实现的类。

此项目引用上面的两个项目。

4.修改web.config

<system.serviceModel>
    <!--<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 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="True"/></behavior></serviceBehaviors></behaviors>-->
    <!--<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />-->
    <!--数据绑定协议-->
    <!--<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />-->
    <bindings>
      <wsHttpBinding>
        <binding name="wdhb" closeTimeout="00:10:00" openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true" maxReceivedMessageSize="2147483647" maxBufferPoolSize="655360000">
          <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647"/>
          <security mode="None"/>
        </binding>
      </wsHttpBinding>
    </bindings>
    <!--数据传输协议-->
    <behaviors>
      <serviceBehaviors>
        <behavior name="bbhr">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" />
          <dataContractSerializer maxItemsInObjectGraph="2147483647" />
        </behavior>
        <behavior name="">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="false" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service behaviorConfiguration="bbhr" name="Services.UserService">
        <endpoint address="" binding="wsHttpBinding" bindingConfiguration="wdhb"
          contract="Contract.IUserService" />
      </service>
      <service behaviorConfiguration="bbhr" name="Services.Calu">
        <endpoint address="" binding="wsHttpBinding" bindingConfiguration="wdhb"
          contract="Contract.ICalu" />
      </service>
    </services>
  </system.serviceModel>

5.新建控制台客户端，引用服务即可。
