UANodeId Constructor(String)

Initializes a new instance of the class, specifying the expanded Id of the node Id.

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
Public Function New( _
   ByVal nodeIdExpandedText As String _
)

'Usage
 
Dim nodeIdExpandedText As String
 
Dim instance As New UANodeId(nodeIdExpandedText)

public UANodeId( 
   string nodeIdExpandedText
)

public:
UANodeId( 
   String^ nodeIdExpandedText
)

Parameters

nodeIdExpandedText

An node Id expanded text (contains namespace URI, and namespace-relative node Id).

The value represents an expanded text of an OPC UA node Id. Any string can be passed to this parameter (i.e. will not cause System.ArgumentException), but not all values make sense and will work when an operation using them is attempted. Example of node Id expanded texts are "nsu=http://test.org/UA/Data/;i=10853" or "ns=1;s=SomeNode".

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

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

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.

Remarks

In languages that support implicit conversions (such as C# or VB.NET), in many cases you do not have call this constructor explicitly. When indicated, a call to an available equivalent implicit conversion operator will be created by the compiler automatically.

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
