oldValue

The value represents an OPC UA namespace URI string. 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.

The value of this parameter cannot be null (Nothing in Visual Basic).

Exceptions
