Opmerkingen

Gebruik deze methode om een Oid object op te halen uit een OidCollection object, als u de locatie ervan kent. U kunt de Item[] eigenschap gebruiken om een Oid object op te halen als u de waarde van de eigenschap of Value eigenschap van het object FriendlyName kent.

Gebruik deze eigenschap om een Oid object op te halen uit een OidCollection object als u de waarde van het Value object of FriendlyName de eigenschap van het Oid object kent. U kunt de Item[] eigenschap gebruiken om een Oid object op te halen als u de locatie ervan in de verzameling weet.
