Gets or sets the upper boundary of the queue modification date and time by which to filter queues on the network.
Assembly: System.Messaging (in System.Messaging.dll)
The application did not set the property before reading it.
A queue's modification flag is set when you change the properties of a queue, but not when a message is read or written to the queue.
The MessageQueueCriteria properties are combined using a logical AND, so setting both and ModifiedAfter bounds a time interval for the queues' last modification. If you set only , there is no lower boundary on the date.
