33.4 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 IDataAdapter {
   // member definitions

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

Public Interface IDataAdapter
   ' member definitions
End Interface

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

public interface IDataReader : IDisposable, IDataRecord

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

Public Interface IDataReader
   Implements IDisposable, IDataRecord
