public ImmutableArray<TOther> CastArray<TOther>()

Initializes a new instance of the ImmutableArray<T> struct by casting the underlying array to an array of type TOther.

public ImmutableArray<T> Clear()

Returns an array with all the elements removed.

public bool Contains(T item)

Determines whether the specified item exists in the array.

public void CopyTo(Span<T> destination)
