MessageQueue.Receive Method (TimeSpan, Cursor, MessageQueueTransaction)

Receives the current message in the queue, using a specified cursor. If no message is available, this method waits until either a message is available, or the time-out expires.

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

public Message Receive(
	TimeSpan timeout,
	Cursor cursor,
	MessageQueueTransaction transaction
)

Parameters

timeout
Type: System.TimeSpan
A TimeSpan that indicates the time to wait until a new message is available for inspection.
cursor
Type: System.Messaging.Cursor
A Cursor that maintains a specific position in the message queue.
transaction
Type: System.Messaging.MessageQueueTransaction
The MessageQueueTransaction object.

Return Value

Type: System.Messaging.Message
A Message that references a message in the queue.

ExceptionCondition
ArgumentNullException

The cursor parameter is null.

-or-

The transaction parameter is null.

ArgumentException

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

MessageQueueException

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

-or-

The queue is non-transactional.

-or-

An error occurred when accessing a Message Queuing method.

Use this overload to receive a message from a transactional queue using the internal transaction context defined by the transaction parameter, and return within a specified period of time if there are no messages in the queue.

The Receive method allows for the synchronous reading of a message, thereby removing it from the queue. Subsequent calls to Receive return the messages that follow in the queue.

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

To read a message in a queue without removing it from the queue, use the Peek method. There is no transaction context associated with a message returned by a call to Peek. Because Peek does not remove any messages in the queue, there is nothing to roll back by a call to Abort.

Use a call to Receive when it is acceptable for the current thread to be blocked while it waits for a message to arrive in the queue. The thread is blocked for the given period of time, or indefinitely if you specified the value InfiniteTimeout for the timeout parameter. If the application processing should continue without waiting for a message, consider using the asynchronous method, BeginReceive.
