MessageQueue.CanWrite Property
Gets a value that indicates whether the MessageQueue can be written to.
Assembly: System.Messaging (in System.Messaging.dll)
[MessagingDescriptionAttribute("MQ_CanWrite")] [BrowsableAttribute(false)] public bool CanWrite { get; }
Property Value
Type: System.Booleantrue if the MessageQueue exists and the application can write to it; otherwise, false.
CanWrite indicates whether the application is able to send messages to the queue. If CanWrite is true, the MessageQueue can send messages to the queue. Otherwise, it cannot.
CanWrite is false if a queue is already open with exclusive write access (or if it's open with non-exclusive access and this MessageQueue requests exclusive access), or if the application does not have sufficient rights to access it. If your application tries to write to a queue when CanWrite is false, access is denied.
