// Create a new message in response to the original message.

// Set the response message's CorrelationId property value to the Id
// property value of the original message.
responseMsg->CorrelationId = id;
// Send the response message to the transactional queue.
transQueue->Send(responseMsg, "Example Response Message Label",

// Set the transactional queue's MessageReadPropertyFilter property to

注解
此方法在 引用MessageQueue的队列中查找与指定correlationId
参数匹配的消息CorrelationId。 如果使用 参数定义的transactionType
事务上下文,具有参数指定的correlationId
相关标识符的消息在队列中,则此方法将立即返回 。 否则, 方法将等待给定的时间段,以便新消息到达。 如果新消息在超时到期之前未到达,则会引发异常。
参数 timeout
不指定此方法的总运行时间。 而是指定等待新消息到达队列的时间。 每当新消息到达时,此方法都会 CorrelationId 检查新消息的 ,以查看它是否与 参数匹配 correlationId
。 否则,此方法将启动超时期限,并等待另一条新消息到达。 因此,如果新消息在超时期限内继续到达,则此方法可能会无限期地继续运行,直到超时期限到期且没有任何新消息到达,或者直到到达与 CorrelationId 参数匹配 correlationId
的消息。 如果已将外部事务上下文附加到要用于接收消息的线程,则为 transactionType
参数指定 Automatic
。 指定 Single
是否要以单个内部事务的形式接收消息。 可以指定 None
是否要从事务上下文之外的事务队列接收消息。
如果调用此方法以接收来自事务队列的消息,则事务中止时收到的消息将返回到队列。 在提交事务之前,不会从队列中永久删除该消息。
属性 CorrelationId 用于将发送到队列的消息绑定到关联的响应、报告或确认消息。
另外两种方法允许从队列接收消息。 方法 Receive 返回队列中的第一条消息,方法 ReceiveById(String) 用于通过指定消息的唯一标识符来检索消息。
若要读取具有指定关联标识符的消息而不将其从队列中删除,请使用 PeekByCorrelationId(String) 方法。 方法 PeekByCorrelationId(String) 始终返回队列中的第一条消息,因此对 方法的后续调用将返回相同的消息,除非队列中到达了更高优先级的消息。 没有与调用 PeekByCorrelationId(String)返回的消息关联的事务上下文。 由于 PeekByCorrelationId(String) 不会删除队列中的任何消息,因此,如果中止事务,则不会回滚任何消息。
下表显示了此方法在各种工作组模式下是否可用。

注解
此方法在 引用MessageQueue的事务队列中查找与指定correlationId
参数匹配的消息CorrelationId。 如果未找到与 参数匹配 correlationID
的消息,则会引发异常。 否则,消息将从队列中删除,并使用 参数定义的 transaction
内部事务上下文返回到应用程序。
由于此方法是在事务队列上调用的,因此,如果事务中止,收到的消息将返回到队列。 在提交事务之前,不会从队列中永久删除该消息。
属性 CorrelationId 用于将发送到队列的消息绑定到关联的响应、报告或确认消息。
另外两种方法允许从队列接收消息。 方法 Receive 返回队列中的第一条消息,方法 ReceiveById(String) 用于通过指定消息的唯一标识符来检索消息。
若要读取具有指定关联标识符的消息而不将其从队列中删除,请使用 PeekByCorrelationId(String) 方法。 方法 PeekByCorrelationId(String) 始终返回队列中的第一条消息,因此对 方法的后续调用将返回相同的消息,除非队列中到达了更高优先级的消息。 没有与调用 PeekByCorrelationId(String)返回的消息关联的事务上下文。 由于 PeekByCorrelationId(String) 不会删除队列中的任何消息,因此,如果中止事务,则不会回滚任何消息。
下表显示了此方法在各种工作组模式下是否可用。

ReceiveByCorrelationId(String)
从非事务性队列中接收与给定的相关标识符匹配的消息,而且在队列中当前不存在具有指定相关标识符的消息时立即引发异常。
public:
System::Messaging::Message ^ ReceiveByCorrelationId(System::String ^ correlationId);
public System.Messaging.Message ReceiveByCorrelationId (string correlationId);
member this.ReceiveByCorrelationId : string -> System.Messaging.Message
Public Function ReceiveByCorrelationId (correlationId As String) As Message
参数
- correlationId
- String
要接收的消息的 CorrelationId。
返回
其 Message 匹配传入的 correlationId
参数的 CorrelationId。
例外
correlationId
参数为 null
。
未能找到具有指定 correlationId
的消息。
访问“消息队列”方法时出错。
示例
下面的代码示例发送和接收一条消息,该消息包含与队列的订单。 它专门在原始消息到达队列或从队列中检索时请求肯定确认。
