Gets the message's identifier.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
Message Queuing (MSMQ) generates a message identifier when the message is sent. The identifier is composed of 20 bytes and includes two items: the machine GUID of the sending computer and a unique identifier for the message on the computer. The combination of the two items produces a message identifier that is unique on the network.
Message Queuing generates message identifiers for all messages, including acknowledgment and report messages. An acknowledgment message is generally sent by Message Queuing in response to the arrival or failure of an original sent message.
