CompareTo(UANodeId) Method



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.AddressSpace Namespace > UANodeId Class > CompareTo Method : CompareTo(UANodeId) Method

Because the UANodeId has an implicit conversion from System.String, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a string (representing the expanded text of the nodeId) in place of this parameter, and the corresponding OPC UA node Id will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the UANodeId Constructor(String) constructor instead.

The value of this parameter can be null (Nothing in Visual Basic).

Syntax
'Declaration

   ByVal other As UANodeId _
) As Integer
'Usage
 
Dim instance As UANodeId
Dim other As UANodeId
Dim value As Integer
 
value = instance.CompareTo(other)
public int CompareTo( 
   UANodeId other
)
public:
int CompareTo( 
   UANodeId^ other
) 

Parameters

other

Because the UANodeId has an implicit conversion from System.String, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a string (representing the expanded text of the nodeId) in place of this parameter, and the corresponding OPC UA node Id will be constructed automatically.

Remarks

This method or property does not throw any exceptions, aside from execution exceptions such as System.Threading.ThreadAbortException or System.OutOfMemoryException.

OPC UA node Id, represented by the UANodeId class, directly identifies a node in a server's address space.

Requirements

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