CreateStandard Method (UANodeId)

Creates a node ID with an identifier in the standard OPC UA namespace.

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
<NotNullAttribute()>
Public Shared Function CreateStandard( _
   ByVal identifier As Object _
) As UANodeId

'Usage
 
Dim identifier As Object
Dim value As UANodeId
 
value = UANodeId.CreateStandard(identifier)

[NotNull()]
public static UANodeId CreateStandard( 
   object identifier
)

[NotNull()]
public:
static UANodeId^ CreateStandard( 
   Object^ identifier
)

Parameters

identifier: Identifier value, either numeric, string, GUID, opaque, or none.
The value of this parameter can be null (Nothing in Visual Basic).

Return Value

Returns the node ID in the standard OPC UA namespace and with the given identifier.

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 (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 never returns null (Nothing in Visual Basic).

Exceptions

Exception	Description
System.ArgumentException	One of the arguments provided to a method is not valid. 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.ArgumentException

One of the arguments provided to a method is not valid.

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

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
