Platform::WriteOnlyArray Class

Represents a one-dimensional array that's used as an input parameter when the caller passes an array for the method to fill.

This ref class is declared as private in vccorlib.h; therefore, it's not emitted in metadata and is only consumable from C++. This class is intended only for use as an input parameter that receives an array that the caller has allocated. It is not constructible from user code. It enables a C++ method to write directly into that array—a pattern that's known as the FillArray pattern. For more information, see Array and WriteOnlyArray (C++/CX).

private ref class WriteOnlyArray<T, 1>

These methods have internal accessibility—that is, they are only accessible within the C++ app or component.
