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 }
