MessageQueue.ReceiveById Method (String, TimeSpan, MessageQueueTransaction)


Receives the message that matches the given identifier (from a transactional queue) and waits until either a message with the specified identifier is available in the queue or the time-out expires.

Namespace:   System.Messaging
Assembly:  System.Messaging (in System.Messaging.dll)

public Message ReceiveById(
	string id,
	TimeSpan timeout,
	MessageQueueTransaction transaction


Type: System.String

The Id of the message to receive.

Type: System.TimeSpan

A TimeSpan that indicates the time to wait until a new message is available for inspection.

Type: System.Messaging.MessageQueueTransaction

The MessageQueueTransaction object.

Return Value

Type: System.Messaging.Message

The Message whose Id property matches the id parameter passed in.

Exception Condition

The id parameter is null.


The transaction parameter is null.


The value specified for the timeout parameter is not valid, possibly timeout is less than TimeSpan.Zero or greater than MessageQueue.InfiniteTimeout.


A message with the specified id did not arrive in the queue before the time-out expired.


The queue is non-transactional.


An error occurred when accessing a Message Queuing method.

Use this method to read a message with a known identifier and remove it from the queue, using the internal transaction context defined by the transaction parameter. This method returns immediately if the message with the identifier specified by the id parameter is in the queue. 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 Id of the new message to see if it matches the id 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 Id matches the id parameter.

The Id property of a message is unique across the Message Queuing enterprise, so there will be at most one message in the queue that matches the given id parameter.

Use this overload of ReceiveById(String) when it is acceptable for the current thread to be blocked as long as new messages continue to arrive in the queue within the time-out period specified by the timeout parameter. The thread will be blocked for at least the given period of time, or indefinitely if you specified the value InfiniteTimeout for the timeout parameter, or if new messages continue to arrive in the queue within the timeout period specified by the timeout parameter.

Because this method is called on 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.

Two other methods allow you to receive messages from a queue. The Receive method returns the first message in the queue, and the ReceiveByCorrelationId(String) method is used to retrieve an acknowledgment, report, or application-generated response message that was created as a result of a message sent to the queue.

To read a message with a specified identifier without removing it from the queue, use the PeekById(String) method. The PeekById(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 PeekById(String). Because PeekById(String) does not remove any messages in the queue, there would be nothing to roll back if the transaction were aborted.

The following code example demonstrates the use of ReceiveById(String, TimeSpan, MessageQueueTransaction).

// Connect to a transactional queue on the local computer.
MessageQueue queue = new MessageQueue(".\\exampleTransQueue");

// Create a new message.
Message msg = new Message("Example Message Body");

// Send the message.
queue.Send(msg, "Example Message Label",

// Get the message's Id property value.
string id = msg.Id;

// Create a message queuing transaction.
MessageQueueTransaction transaction = new MessageQueueTransaction();

    // Begin a transaction.

    // Receive the message from the queue.
    msg = queue.ReceiveById(id, TimeSpan.FromSeconds(10.0),

    // Commit the transaction.
catch(System.Exception e)
    // Cancel the transaction.

    // Propagate the exception.
    throw e;
    // Dispose of the transaction object.
