Given a non-generic IEnumerable interface, wrap a generic IEnumerable<T> interface around it. The generic interface will enumerate the same objects as the underlying non-generic collection, but can be used in places that require a generic interface. The underlying non-generic collection must contain only items that are of type T or a type derived from it. This method is useful when interfacing older, non-generic collections to newer code that uses generic interfaces.

public static IEnumerable<T> TypedAs<T>(
	IEnumerable untypedCollection
)

public:
generic<typename T>
static IEnumerable<T>^ TypedAs(
	IEnumerable^ untypedCollection
)
