Poznámky

Typy aktivované serverem můžou být buď jedno volání, nebo jednoúčelové volání. Pokud je třída zaregistrovaná jako jeden typ volání, vytvoří se při každém volání z klienta nová instance. Všechna volání jednoúčelového objektu jsou zpracována jednou instancí tohoto objektu, pokud tento objekt nebyl shromážděn.

Každý klient, který zná identifikátor URI zaregistrovaného objektu aktivovaného serverem, může získat proxy pro tento objekt registrací kanálu, který ChannelServices preferuje, a aktivací objektu voláním new nebo Activator.GetObject. Chcete-li aktivovat objekt aktivovaný serverem pomocí new, musíte nejprve zaregistrovat typ objektu aktivovaného serverem v klientovi pomocí RegisterWellKnownClientType metody . Voláním RegisterWellKnownClientTypeobjektu dáváte infrastruktuře vzdálené komunikace umístění vzdáleného objektu, což umožňuje jeho vytvoření pomocí klíčového new slova. Pokud naopak použijete metodu Activator.GetObject k aktivaci objektu aktivovaného serverem, musíte mu jako argument zadat adresu URL objektu, takže není nutná žádná předchozí registrace na klientovi.

Podrobný popis objektů aktivovaných serverem a vzdálené aktivace objektů najdete v tématu Aktivace vzdálených objektů.
