An node Id expanded text (contains namespace URI, and namespace-relative node Id).
The value represents an expanded text of an OPC UA node Id. Any string can be passed to this parameter (i.e. will not cause System.ArgumentException), but not all values make sense and will work when an operation using them is attempted. Example of node Id expanded texts are "nsu=http://test.org/UA/Data/;i=10853" or "ns=1;s=SomeNode".
The value of this parameter cannot be null
(Nothing
in Visual Basic).
Initializes a new instance of the class, specifying the expanded Id of the node Id.
