Příklady

Následující příklad kódu ukazuje, jak definovat a používat dynamické sestavení. Příklad sestavení obsahuje jeden typ, MyDynamicType, který má privátní pole, vlastnost, která získá a nastaví privátní pole, konstruktory inicializují privátní pole a metodu, která vynásobí uživatelem zadané číslo hodnotou privátního pole a vrátí výsledek.

    // a user-supplied number by the private field value and returns
    // the result. In Visual C++ the type might look like this:
