Opmerkingen
Gebruik deze overbelasting als u een volledige lijst met alle openbare wachtrijen op het netwerk wilt. Als u de lijst wilt beperken op basis van bepaalde criteria, zoals MachineName, Categoryof de laatste wijzigingstijd, gebruikt u een andere overbelasting van deze methode. (U kunt GetPublicQueuesByMachine(String)ook gebruiken, GetPublicQueuesByCategory(Guid)of GetPublicQueuesByLabel(String).)
GetPublicQueues haalt een statische momentopname van de wachtrijen op. Als u wilt communiceren met een dynamische lijst met de wachtrijen, gebruikt u GetMessageQueueEnumerator.

Opmerkingen
Als u alle openbare wachtrijen op het netwerk wilt filteren op label, categorie of computernaam, bevat de MessageQueue klasse specifieke methoden die die functionaliteit bieden (GetPublicQueuesByLabel(String)respectievelijk GetPublicQueuesByCategory(Guid), en GetPublicQueuesByMachine(String), ). Gebruik deze overbelasting om een lijst op te halen met alle openbare wachtrijen in het netwerk die voldoen aan meer dan een van deze criteria (bijvoorbeeld als u zowel een label als een categorie wilt opgeven). U kunt ook filteren op andere berichtcriteria dan Label, Categoryen MachineName. U gebruikt deze overbelasting bijvoorbeeld om te filteren op de laatst gewijzigde tijd van een wachtrij. Maak gewoon een nieuw exemplaar van de MessageQueueCriteria klasse, stel de juiste eigenschappen in het exemplaar in en geef het exemplaar door als de criteria parameter.
GetPublicQueues haalt een statische momentopname van de wachtrijen op. Als u wilt communiceren met een dynamische lijst met de wachtrijen, gebruikt u GetMessageQueueEnumerator.
