Match(UANodeId) Method

Determines whether the node Id matches another node Id.

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
Public Overloads Function Match( _
   ByVal other As UANodeId _
) As Boolean

'Usage
 
Dim instance As UANodeId
Dim other As UANodeId
Dim value As Boolean
 
value = instance.Match(other)

public bool Match( 
   UANodeId other
)

public:
bool Match( 
   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. When the implicit conversion operators are not supported (such as with Python.NET), you can use the UANodeId Constructor(String) constructor instead.

A UANodeId object. The node Id to match against.

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

Return Value

Returns true if two node Ids match; otherwise, returns false.

Exceptions

Exception Description

Exception	Description
System.ArgumentNullException	A `null` reference (`Nothing` in Visual Basic) is passed to a method that does not accept it as a valid argument. This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.

System.ArgumentNullException

Remarks

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

For a match, identifiers must equal, but namespaces must equal only if present in both node Ids.

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
