22.4 Interfaces

C# uses the interface statement along with opening and closing braces to indicate the beginning and end of an interface definition. For example:

public interface IUIService {
   // member definitions
}

In VB, an interface definition is indicated by the Interface... End Structure construct:

Public Interface IUIService
   ' member definitions
End Interface

C# uses the colon with interfaces to specify any implemented interfaces. For example:

public interface ISite : IServiceProvider

In VB, any implemented interfaces are specified by an Implements statement on the line immediately following the Interface statement. Hence, the previous definition of ISite in C# would appear as follows in VB:

Public Interface ISite
   Implements IServiceProvider
