Type.BaseType Property

Gets the type from which the current Type directly inherits.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

abstract BaseType : Type

Property Value

Type: System.Type
The Type from which the current Type directly inherits, or a null reference (Nothing in Visual Basic) if the current Type represents the Object class or an interface.

Implements

_Type.BaseType

The base type is the type from which the current type directly inherits. Object is the only type that does not have a base type, therefore a null reference (Nothing in Visual Basic) is returned as the base type of Object.

Interfaces inherit from zero or more base interfaces; therefore, this property returns a null reference (Nothing in Visual Basic) if the Type object represents an interface. The base interfaces can be determined with GetInterfaces or FindInterfaces.

If the current Type represents a constructed generic type, the base type reflects the generic arguments. For example, consider the following declarations:

No code example is currently available or this language may not be supported.

For the constructed type C<int> (C(Of Integer) in Visual Basic), the BaseType property returns B<int>.

If the current Type represents a type parameter of a generic type definition, BaseType returns the class constraint, that is, the class the type parameter must inherit. If there is no class constraint, BaseType returns System.Object.

This property is read-only.

The following example demonstrates using the BaseType property.
