The latest version of this topic can be found at typeof Goes to T::typeid.
The typeof operator used in Managed Extensions for C++ has been supplanted by the typeid keyword in Visual C++.
In Managed Extensions, the __typeof() operator returns the associated Type* object when passed the name of a managed type. For example:
// Creates and initializes a new Array instance.
Array* myIntArray =
Array::CreateInstance( __typeof(Int32), 5 );
In the new syntax, __typeof has been replaced by an additional form of typeid that returns a Type^ when a managed type is specified.
// Creates and initializes a new Array instance.
Array^ myIntArray =
Array::CreateInstance( Int32::typeid, 5 );
