two values of different types inside one object.
|
![]() | Type | Represents type declarations: class types, interface types, array types, value types, enumeration types, type parameters, generic type definitions, and open or closed constructed generic types. |
![]() | Uri |
Provides an object representation of a uniform resource identifier (URI)
and easy access to the parts of the URI.
