Deletes the messages in a queue specified by the QueueURL parameter.

When you use the PurgeQueue action, you can't retrieve a message deleted from a queue.

When you purge a queue, the message deletion process takes up to 60 seconds. All messages sent to the queue before calling the PurgeQueue action are deleted. Messages sent to the queue while it is being purged might be deleted. While the queue is being purged, messages sent to the queue before PurgeQueue is called might be received, but are deleted within the next minute.


This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginPurgeQueue and EndPurgeQueue. For Unity the operation does not take CancellationToken as a parameter, and instead takes AmazonServiceCallback<PurgeQueueRequest, PurgeQueueResponse> and AsyncOptions as additional parameters.

Assembly: AWSSDK.SQS.dll

Type: System.String
