Property Value

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

Because there are implicit conversions to OpcLabs.EasyOpc.UA.Navigation.UANamedNodeDescriptor and OpcLabs.EasyOpc.UA.Navigation.UANamedNodePath from OpcLabs.EasyOpc.UA.UANodeDescriptor, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use the returned OpcLabs.EasyOpc.UA.UANodeDescriptor in any place where OpcLabs.EasyOpc.UA.Navigation.UANamedNodeDescriptor is expected (in this case the OpcLabs.EasyOpc.UA.UANodeDescriptor contains the final node descriptor) or where OpcLabs.EasyOpc.UA.Navigation.UANamedNodePath is expected (in this case the OpcLabs.EasyOpc.UA.UANodeDescriptor contains the base and only node in the named node path), and the corresponding OPC UA named node descriptor or named node path will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the FromUANodeDescriptor or FromUANodeDescriptor static method instead.

Remarks

This method or property does not throw any exceptions, aside from execution exceptions such as System.Threading.ThreadAbortException or System.OutOfMemoryException.
