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

Definition

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.

public:
generic <typename TDerived>
 where TDerived : class, T static System::Collections::Immutable::ImmutableArray<T> CastUp(System::Collections::Immutable::ImmutableArray<TDerived> items);
public static System.Collections.Immutable.ImmutableArray<T> CastUp<TDerived> (System.Collections.Immutable.ImmutableArray<TDerived> items) where TDerived : class, T;
static member CastUp : System.Collections.Immutable.ImmutableArray<#'T> -> System.Collections.Immutable.ImmutableArray<'T>
Public Shared Function CastUp(Of TDerived As {Class, T}) (items As ImmutableArray(Of TDerived)) As ImmutableArray(Of T)

Type Parameters

TDerived

Parameters

items
ImmutableArray<TDerived>

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

Returns

Remarks

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