rank

Int32

Počet dimenzí pole.

Návraty

Type

Příklady

Následující příklad kódu vytvoří dynamický modul, abstraktní obecný typ s názvem Sample s jedním parametrem Ttypu a abstraktní metodu s názvem TestMethod. TestMethod ref přebírá parametr (ByRefv jazyce Visual Basic) typu T, ukazatel na typ Ta pole T. Tato metoda vrátí dvojrozměrnou matici T. Příklad kódu uloží dynamický modul na disk, abyste ho mohli prozkoumat pomocí nástroje MSIL Disassembler (Ildasm.exe).
