NumericIdentifier Property (_UANodeId)



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.AddressSpace.ComTypes Namespace > _UANodeId Interface : NumericIdentifier Property
Numeric identifier value, expressed as signed integer.
Syntax
'Declaration
 
Property NumericIdentifier As Integer
'Usage
 
Dim instance As _UANodeId
Dim value As Integer
 
instance.NumericIdentifier = value
 
value = instance.NumericIdentifier
int NumericIdentifier {get; set;}
property int NumericIdentifier {
   int get();
   void set (    int value);
}
Remarks
The actual OPC-UA numeric identifier is a 32-bit unsigned integer. For .NET clients, we expose it as 64-bit signed integer, which is CLS compliant and holds it fully. In this interface, however, a 32-bit signed value is used, for clients such as Visual Basic 6. The value is cast unchecked. Consequently, beware of the possible differences between the .NET and COM clients.

This member or type is for use from COM. It is not meant to be used from .NET or Python. Refer to the corresponding .NET member or type instead, if you are developing in .NET or Python.

Requirements

Target Platforms: .NET Framework: Windows 10 (selected versions), Windows 11 (selected versions), Windows Server 2016, Windows Server 2022; .NET: Linux, macOS, Microsoft Windows
