A.4. Interfaces

Table of contents:

A 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 Interface 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
