Implements Clause (Visual Basic)

Indicates that a class or structure member is providing the implementation for a member defined in an interface.

The Implements keyword is not the same as the Implements Statement. You use the Implements statement to specify that a class or structure implements one or more interfaces, and then for each member you use the Implements keyword to specify which interface and which member it implements.

If a class or structure implements an interface, it must include the Implements statement immediately after the Class Statement (Visual Basic) or Structure Statement, and it must implement all the members defined by the interface.

Reimplementation

In a derived class, you can reimplement an interface member that the base class has already implemented. This is different from overriding the base class member in the following respects:

  • The base class member does not need to be Overridable (Visual Basic) to be reimplemented.

  • You can reimplement the member with a different name.

The Implements keyword can be used in these contexts:

Event Statement

Function Statement (Visual Basic)

Property Statement

Sub Statement (Visual Basic)
