Kommentarer

Serveraktiverade typer kan vara antingen enkla anrop eller singleton. Om en klass registreras som en enda samtalstyp skapas en ny instans varje gång ett anrop från klienten tas emot. Alla anrop till ett singleton-objekt hanteras av en instans av objektet, såvida inte objektet har samlats in.

Alla klienter som känner till URI:n för ett registrerat serveraktiverat objekt kan hämta en proxy för det här objektet genom att registrera kanalen som den föredrar med ChannelServices och aktivera objektet genom att anropa new eller Activator.GetObject. Om du vill aktivera ett serveraktiverat objekt med newmåste du först registrera den serveraktiverade objekttypen på klienten med hjälp av RegisterWellKnownClientType metoden . Genom att anropa RegisterWellKnownClientTypeger du fjärrkommunikationsinfrastrukturen platsen för fjärrobjektet, vilket gör att nyckelordet new kan skapa det. Om du å andra sidan använder Activator.GetObject metoden för att aktivera ett serveraktiverat objekt måste du ange det med objektets URL som argument, så ingen förhandsregistrering på klienten krävs.

En detaljerad beskrivning av serveraktiverade objekt och aktivering av fjärrobjekt finns i Aktivering av fjärrobjekt.
