ImmutableArray<T>::CastUp<TDerived> Method (ImmutableArray<TDerived>)

Initializes a new instance of the ImmutableArray<T> struct based on the contents of an existing instance, allowing a covariant static cast to efficiently reuse the existing array.

Namespace: System.Collections.Immutable
Assembly: System.Collections.Immutable (in System.Collections.Immutable.dll)

where TDerived : ref class, T
static ImmutableArray<T> CastUp(
	ImmutableArray<TDerived> items
)

The array to initialize the array with. No copy is made.

Return Value

Type: System.Collections.Immutable::ImmutableArray<T>

Type Parameters

TDerived

Remarks

Covariant upcasts from this method may be reversed by calling the As<TOther> or CastArray<TOther>method.
