// property value of the original message.
responseMsg->CorrelationId = id;

// Send the response message to the transactional queue.
transQueue->Send(responseMsg, "Example Response Message Label",
    MessageQueueTransactionType::Single);

// Set the transactional queue's MessageReadPropertyFilter property to
// ensure that the response message includes the desired properties.
transQueue->MessageReadPropertyFilter->CorrelationId = true;

// Receive the response message from the transactional queue.
responseMsg = transQueue->ReceiveByCorrelationId(id,
    TimeSpan::FromSeconds(10.0), MessageQueueTransactionType::Single);

// Display the response message's property values.
Console::WriteLine("Message.Label: {0}", responseMsg->Label);
Console::WriteLine("Message.CorrelationId: {0}",
    responseMsg->CorrelationId);

transQueue->Close();

// Send the message to the nontransactional queue.

Console.WriteLine("Message.CorrelationId: {0}",
    responseMsg.CorrelationId);

Remarks

This method looks in the queue referenced by the MessageQueue for a message whose CorrelationId matches the specified correlationId parameter. This method returns immediately if the message with the correlation identifier specified by the correlationId parameter is in the queue, using a transaction context defined by the transactionType parameter. Otherwise, the method waits the given period of time for a new message to arrive. If a new message does not arrive before the time-out expires, an exception is thrown.

The timeout parameter does not specify the total running time for this method. Rather, it specifies the time to wait for a new message to arrive in the queue. Each time a new message arrives, this method examines the CorrelationId of the new message to see if it matches the correlationId parameter. If not, this method starts the time-out period over and waits for another new message to arrive. Therefore, if new messages continue to arrive within the time-out period, it is possible for this method to continue running indefinitely, either until the time-out period expires without any new messages arriving, or until a message arrives whose CorrelationId matches the correlationId parameter. Specify Automatic for the transactionType parameter if there is already an external transaction context attached to the thread that you want to use to receive the message. Specify Single if you want to receive the message as a single internal transaction. You can specify None if you want to receive a message from a transactional queue outside of a transaction context.

If this method is called to receive a message from a transactional queue, the message that is received would be returned to the queue if the transaction is aborted. The message is not permanently removed from the queue until the transaction is committed.

The CorrelationId property is used to tie a message sent to the queue to associated response, report, or acknowledgment messages.

Two other methods allow you to receive messages from a queue. The Receive method returns the first message in the queue, and the ReceiveById(String) method is used to retrieve a message by specifying its unique identifier.

To read a message with a specified correlation identifier without removing it from the queue, use the PeekByCorrelationId(String) method. The PeekByCorrelationId(String) method always returns the first message in the queue, so subsequent calls to the method return the same message unless a higher priority message arrives in the queue. There is no transaction context associated with a message returned by a call to PeekByCorrelationId(String). Because PeekByCorrelationId(String) does not remove any messages in the queue, there would be nothing to roll back if the transaction were aborted.

Remarks

This method looks in the transactional queue referenced by the MessageQueue for a message whose CorrelationId matches the specified correlationId parameter. If no message is found that matches the correlationID parameter, an exception is thrown. Otherwise, the message is removed from the queue and returned to the application using the internal transaction context defined by the transaction parameter.

The CorrelationId property is used to tie a message sent to the queue to associated response, report, or acknowledgment messages.

The following table shows whether this method is available in various Workgroup modes.

Workgroup mode	Available
Local computer	Yes
Local computer and direct format name	Yes
Remote computer	No
Remote computer and direct format name	Yes

Applies to

ReceiveByCorrelationId(String)

Receives the message that matches the given correlation identifier (from a non-transactional queue) and immediately raises an exception if no message with the specified correlation identifier currently exists in the queue.

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

Parameters

correlationId: String

The CorrelationId of the message to receive.

Returns

Message

The Message whose CorrelationId matches the correlationId parameter passed in.

Exceptions

ArgumentNullException

The correlationId parameter is null.

InvalidOperationException

The message with the specified correlationId could not be found.

MessageQueueException

An error occurred when accessing a Message Queuing method.

Examples

The following code example sends and receives a message that contains an order to and from a queue. It specifically requests a positive acknowledgment when the original message reaches or is retrieved from the queue.

Remarks

This method looks in the non-transactional queue referenced by the MessageQueue for a message whose CorrelationId matches the specified correlationId parameter. If no message is found that matches the correlationID parameter, an exception is thrown. Otherwise, the message is removed from the queue and returned to the application.

The CorrelationId property is used to tie a message sent to the queue to associated response, report, or acknowledgment messages.

Two other methods allow you to receive messages from a queue. The Receive method returns the first message in the queue, and the ReceiveById(String) method retrieves a message by specifying its unique identifier.

The following table shows whether this method is available in various Workgroup modes.

Workgroup mode	Available
Local computer	Yes
Local computer and direct format name	Yes
Remote computer	No
Remote computer and direct format name	Yes
