ReadOnlySpanMarshaller<T,TUnmanagedElement> Класс

Определение

Важно!

Этот API несовместим с CLS.

Поддерживает маршаллирование ReadOnlySpan<T> управляемого значения в непрерывный собственный массив неуправляемых значений элементов.

Комментарии

Маршал ReadOnlySpan<T> с этим маршаллером будет соответствовать семантике GetReference<T>(ReadOnlySpan<T>). В частности, этот маршаллизатор будет передавать не-значениеnull для нулевого диапазона длины, если диапазон был построен с незначаемойnull .
