'Declaration
<CanBeNullAttribute()> <ContractAnnotationAttribute("null => null; notnull => notnull")> Overloads Public Operator Narrowing CType( _ ByVal nodeElement As UANodeElement _ ) As UANodeId
'Usage
[CanBeNull()] [ContractAnnotation("null => null; notnull => notnull")] public UANodeId operator explicit( UANodeElement nodeElement )
[CanBeNull()] [ContractAnnotation("null => null; notnull => notnull")] public: UANodeId^ operator explicit( UANodeElement^ nodeElement )
Parameters
- nodeElement
- The node element to be converted.
The value of this parameter can be
null
(Nothing
in Visual Basic).
Return Value
null
if the input is null
.
Because there is an implicit conversion from UANodeId to OpcLabs.EasyOpc.UA.UANodeDescriptor, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use the returned UANodeId in any place where the OpcLabs.EasyOpc.UA.UANodeDescriptor is expected as input, and the corresponding node descriptor will be constructed automatically.
Also, because the UANodeId has an implicit conversion to System.String, and it converts to the expanded text of the node Id (UANodeId.ExpandedText), in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use the returned UANodeId in any place where expanded text of a node Id (a string) is expected as input, and the corresponding expanded text will be taken automatically from the node Id.
This method can return null
(Nothing
in Visual Basic).
