MessageQueue::CanRead Property
Gets a value that indicates whether the MessageQueue can be read.
Assembly: System.Messaging (in System.Messaging.dll)
public: [BrowsableAttribute(false)] [MessagingDescriptionAttribute("MQ_CanRead")] property bool CanRead { bool get(); }
Property Value
Type: System::Booleantrue if the MessageQueue exists and the application can read from it; otherwise, false.
CanRead indicates whether the application is able to peek or receive messages from the queue. If CanRead is true, the MessageQueue can receive or peek messages from the queue. Otherwise, it cannot.
CanRead is false if a queue is already open with exclusive read 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 read from a queue when CanRead is false, access is denied.
