MessageQueue.Receive Method ()


Receives the first message available in the queue referenced by the MessageQueue. This call is synchronous, and blocks the current thread of execution until a message is available.

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

public Message Receive()

Return Value

Type: System.Messaging.Message

A Message that references the first message available in the queue.

Exception Condition

An error occurred when accessing a Message Queuing method.

Use this overload to receive a message from a queue, or wait until there are 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 will return the messages that follow in the queue, or new, higher priority messages.

To read the first message in a queue without removing it from the queue, use the Peek method. The Peek 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.

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. Because this overload of the Receive method specifies an infinite time-out, the application might wait indefinitely. If the application processing should continue without waiting for the message, consider using the asynchronous method, BeginReceive.

The following code example receives a message from a queue and outputs information about that message to the screen.
