Name
Inherits Statement
Syntax
Inherits classname
-
classname
(required; String literal) The name of the inherited (base) class
Description
Specifies the name of the class that is being inherited, that is, the
base class. The statement can appear immediately after the
Class
statement or the
Interface
statement.
Rules at a Glance
The
Inherits
statement must be the first line of code in the class module. It can be preceeded only by blank lines or comments. For example:Public Class CDerivedClass Inherits CBaseClass ...
VB.NET supports single code-based inheritance only. That is, there can be only a single
Inherits
statement in any class module.If the
Inherits
statement is used to define the interfaces inherited by an interface, multiple interfaces can be listed, with a comma used to delimit them. For example:Interface IPerson Property Name As String End Interface Interface IEmployee Property SSN As String End Interface Interface ISalaried Inherits IPerson, IEmployee Property Salaried As Boolean Property Salary As Decimal End Interface
Programming Tips and Gotchas
The Inherits
statement implements code
inheritance. You can also use the Implements
statement to implement interface inheritance. In that case, a class
can be derived from more than one virtual base class. (In other
words, you can effectively implement multiple inheritance through
interface inheritance using the Implements
statement.)
