wcfServiceObject：这不能转换错误

Question

行wcfServiceObject:this给出了一个错误cannot convert from ... to ...。

return new[] { new ServiceReplicaListener((context) => 
    new WcfCommunicationListener<IShoppingCartService>(
     wcfServiceObject:this, 
     serviceContext:context, 
     // 
     // The name of the endpoint configured in the ServiceManifest under the Endpoints section 
     // that identifies the endpoint that the WCF ServiceHost should listen on. 
     // 
     endpointResourceName: "WcfServiceEndpoint", 

     // 
     // Populate the binding information that you want the service to use. 
     // 
     listenerBinding: WcfUtility.CreateTcpListenerBinding() 
    ) 
)}; 

如何解决此问题？

Answer 1

我想，我应该实现interface为我服务。像下面的ShoppingCartService的例子：

internal sealed class ShoppingCartService : StatefulService, IShoppingCartService 
{ 
    ... 
} 

在这种特殊情况下，我不得不实施IShoppingCartService接口，为ShoppingCartService。
