Read-only property

Public Property LastInstanceUID As String

Although this property could be used for checking the UID involved in any normalised operation, its primary purpose is to allow retrieval of the UID of the object created in response to an NCreate operation.
This property contain the result of an outgoing operation on the DicomConnection, and if Mode is doAsync or doNoSync, it is therefore valid only once the operation is signaled as completed, either through the ActionComplete event, use of the Wait method, or when isReady is true.
