Gets or sets the category by which to filter queues in the network.
Assembly: System.Messaging (in System.Messaging.dll)
The application did not set the property before reading it.
The queue category allows an application to categorize its queues. For example, you can place all Billing queues in one category and all Order queues in another. The Category property is application-defined and has no intrinsic meaning to Message Queuing.
If you are filtering only by category when searching the queues on the network, you can use the method GetPublicQueuesByCategory, which is specifically designed for this purpose. If you are searching by multiple criteria that include the category, set this property and pass the parameter into GetPublicQueues.
