Property Value

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

Because the OpcLabs.EasyOpc.UA.AddressSpace.UAQualifiedName has an implicit conversion to System.String, and it converts to the expanded text of the qualified name (ExpandedText), in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use the returned OpcLabs.EasyOpc.UA.AddressSpace.UAQualifiedName in any place where expanded text of a qualified name (a string) is expected as input, and the corresponding expanded text will be taken automatically from the qualified name.

Also, because the OpcLabs.EasyOpc.UA.Navigation.UABrowsePathElement has an implicit conversion from OpcLabs.EasyOpc.UA.AddressSpace.UAQualifiedName, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use the returned OpcLabs.EasyOpc.UA.AddressSpace.UAQualifiedName (containing a target qualified name, which becomes the "any hierarchical" forward reference) in any place where OpcLabs.EasyOpc.UA.Navigation.UABrowsePathElement is expected as input, and the corresponding OPC UA browse path element will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the OpcLabs.EasyOpc.UA.Navigation.UABrowsePathElement.FromUAQualifiedName static method instead.

Also, because the OpcLabs.EasyOpc.UA.UAReadParameters has an implicit conversions from OpcLabs.EasyOpc.UA.AddressSpace.UAQualifiedName, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply the returned OpcLabs.EasyOpc.UA.AddressSpace.UAQualifiedName (representing the name of the encoding to be used) in any place where OpcLabs.EasyOpc.UA.UAReadParameters is expected as input, and the corresponding OPC UA read parameters will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the FromDouble or FromUAQualifiedName static method instead.
