備註
這個方法會在 所參考MessageQueue的佇列中尋找符合指定correlationId
參數的CorrelationId訊息。 如果使用 參數所定義的交易內容,則這個方法會立即傳回具有參數所指定 correlationId
相互關聯標識符的 transactionType
訊息。 否則,方法會等候指定的時間週期,讓新訊息送達。 如果在逾時到期之前未送達新訊息,則會擲回例外狀況。
參數 timeout
未指定這個方法的總運行時間。 相反地,它會指定等候新訊息抵達佇列的時間。 每次新訊息送達時,這個方法都會 CorrelationId 檢查新訊息的 ,以查看它 correlationId
是否符合 參數。 如果沒有,這個方法會開始逾時期間,並等候另一個新訊息送達。 因此,如果新訊息繼續在逾時期間內送達,則此方法可以無限期地繼續執行,直到逾時期間到期,而不會到達任何新訊息,或直到訊息到達符合 CorrelationId 參數的 correlationId
訊息為止。 Automatic
如果已經附加至您要用來接收訊息之線程的外部交易內容,請指定 transactionType
參數。 指定 Single
是否要以單一內部交易的形式接收訊息。 您可以指定 None
是否要從交易內容外部的交易佇列接收訊息。
如果呼叫這個方法以接收來自交易佇列的訊息,如果交易已中止,則收到的訊息會傳回至佇列。 在認可交易之前,不會從佇列永久移除訊息。
屬性 CorrelationId 用來將傳送至佇列的訊息系結至相關聯的回應、報告或通知訊息。
其他兩種方法可讓您從佇列接收訊息。 方法 Receive 會傳回佇列中的第一個訊息,而 ReceiveById(String) 方法會藉由指定其唯一標識符來擷取訊息。
若要讀取具有指定相互關聯標識碼的訊息,而不從佇列中移除它,請使用 PeekByCorrelationId(String) 方法。 方法 PeekByCorrelationId(String) 一律會傳回佇列中的第一個訊息,因此除非佇列中有較高的優先順序訊息,否則對方法的後續呼叫會傳回相同的訊息。 呼叫 所 PeekByCorrelationId(String)傳回的訊息沒有相關聯的交易內容。 由於 PeekByCorrelationId(String) 不會移除佇列中的任何訊息,因此如果交易中止,則不會復原任何訊息。

是否符合 參數。 如果沒有,這個方法會開始逾時期間,並等候另一個新訊息送達。 因此,如果新訊息繼續在逾時期間內送達,則此方法可以無限期地繼續執行,直到逾時期間到期,而不會到達任何新訊息,或直到訊息到達符合 CorrelationId 參數的 correlationId
訊息為止。
因為這個方法是在交易佇列上呼叫,所以如果交易已中止,就會將收到的訊息傳回至佇列。 在認可交易之前,不會從佇列永久移除訊息。

備註
這個方法會在所MessageQueue參考的交易佇列中尋找符合指定correlationId
參數的CorrelationId訊息。 如果找不到符合 參數的 correlationID
訊息,則會擲回例外狀況。 否則,訊息會從佇列中移除,並使用 參數所 transaction
定義的內部交易內容傳回應用程式。
因為這個方法是在交易佇列上呼叫,所以如果交易已中止,就會將收到的訊息傳回至佇列。 在認可交易之前,不會從佇列永久移除訊息。
屬性 CorrelationId 用來將傳送至佇列的訊息系結至相關聯的回應、報告或通知訊息。
其他兩種方法可讓您從佇列接收訊息。 方法 Receive 會傳回佇列中的第一個訊息,而 ReceiveById(String) 方法會藉由指定其唯一標識符來擷取訊息。
若要讀取具有指定相互關聯標識碼的訊息,而不從佇列中移除它,請使用 PeekByCorrelationId(String) 方法。 方法 PeekByCorrelationId(String) 一律會傳回佇列中的第一個訊息,因此除非佇列中有較高的優先順序訊息,否則對方法的後續呼叫會傳回相同的訊息。 呼叫 所 PeekByCorrelationId(String)傳回的訊息沒有相關聯的交易內容。 由於 PeekByCorrelationId(String) 不會移除佇列中的任何訊息,因此如果交易中止,則不會復原任何訊息。
