用VisualStudio2010学习WCF服务编程总结（2）契约的继承

契约的设计

 1 namespace MyService
 2 {
 3     [ServiceContract]
 4     public interface IPerson
 5     {
 6         [OperationContract]
 7         string Say(string say);
 8     }
 9     [ServiceContract]
10     public interface IStudent : IPerson
11     {
12         [OperationContract]
13         string Study(string study);
14     }
15 }

 契约的服务类型

 1 namespace MyService
 2 {
 3     public class Service1 : IStudent
 4     {
 5         public string Study(string study)
 6         {
 7             return "2." + study;
 8         }
 9 
10         public string Say(string say)
11         {
12             return "1."+say;
13         }
14     }
15 }

配置文件

 1 <system.serviceModel>
 2     <services>
 3       <service behaviorConfiguration="MyService.Service1Behavior" name="MyService.Service1">
 4         <endpoint address="" binding="wsHttpBinding" contract="MyService.IStudent">
 5           <identity>
 6             <dns value="localhost" />
 7           </identity>
 8         </endpoint>
 9         <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
10       </service>
11     </services>
12     <behaviors>
13       <serviceBehaviors>
14         <behavior name="MyService.Service1Behavior">
15           <serviceMetadata httpGetEnabled="true"/>
16           <serviceDebug includeExceptionDetailInFaults="false"/>
17         </behavior>
18       </serviceBehaviors>
19     </behaviors>
20   </system.serviceModel>
