Parameters
- expandedText
- Expanded text of the qualified name.
The value of this parameter cannot be
null(Nothingin Visual Basic). - defaultNamespaceUriString
- The default namespace to be used if no namespace is specified in the input string.
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 can be
null(Nothingin Visual Basic).
Return Value
Because the 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 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 UAQualifiedName, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use the returned 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 UAQualifiedName, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply the returned 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.
This method never returns null (Nothing in Visual Basic).
