Příklady

Následující příklad vytvoří instanci objektu Timer , který aktivuje svou Timer.Elapsed událost každé dvě sekundy (2000 milisekund), nastaví obslužnou rutinu události pro událost a spustí časovač. Obslužná rutina události zobrazí hodnotu ElapsedEventArgs.SignalTime vlastnosti při každém jejím vyvolání.

Vlastnosti

SignalTime

Získá datum a čas, kdy Elapsed byla událost vyvolána.

Metody

Equals(Object)	Určí, zda se zadaný objekt rovná aktuálnímu objektu. (Zděděno od Object)
GetHashCode()	Slouží jako výchozí hashovací funkce. (Zděděno od Object)
GetType()	Type Získá z aktuální instance. (Zděděno od Object)
MemberwiseClone()	Vytvoří mělkou kopii aktuálního Objectsouboru . (Zděděno od Object)
ToString()	Vrátí řetězec, který představuje aktuální objekt. (Zděděno od Object)
