Public propertyCorrelationID
Gets the correlationId associated with this message.
Public propertyCorrelationIDs
Gets an enumerable collection of all collectionIds associated with this message.
Public propertyElements
Gets the enumerable collection of elements.
Public propertyFragmentType
Gets the fragment type of this message.
Public propertyIsValid
Return true if the message is valid.

Remarks
Message objects are used to represent all outputs from the API including subscription data, response, administrative and status messages. Message objects are obtained from Event.GetMessages(). A message always has a message type and may optionally contain the following
TopicNameValid for Subscription data messages.
ServiceThe service from which this message was received from.
CorrelationIdOne or more correlationIds if this message was delivered for a pending request or a subscription.

A Message object is a handle to a single underlying protocol message. The Message contents are represented as an Element and some convenient shortcuts are supplied to the Element accessors.

Thread Safety
Static members of this type are safe for multi-threaded operations. Instance members of this type are safe for multi-threaded operations.
