'Usage

[DataMember()]

Property Value

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

The individual elements of the property value cannot be null (Nothing in Visual Basic).

Because the OpcLabs.EasyOpc.UA.Navigation.UABrowsePathElementCollection has an implicit conversion from OpcLabs.EasyOpc.UA.AddressSpace.UAQualifiedNameCollection, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use the returned OpcLabs.EasyOpc.UA.AddressSpace.UAQualifiedNameCollection (containing a sequence of qualified names, assumed to form a relative browse path using "any hierarchical" forward references) in any place where OpcLabs.EasyOpc.UA.Navigation.UABrowsePathElementCollection is expected as input, and the corresponding OPC UA browse path element collection 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.UABrowsePathElementCollection.FromUAQualifiedNameCollection static method instead.
