FromUABuiltInType Method

Converts the OPC UA build-in type (an enumeration) to the node Id that is its corresponding data type Id.

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
<NotNullAttribute()>
Public Shared Function FromUABuiltInType( _
   ByVal builtInType As UABuiltInType _
) As UANodeId

'Usage
 
Dim builtInType As UABuiltInType
Dim value As UANodeId
 
value = UANodeId.FromUABuiltInType(builtInType)

[NotNull()]
public static UANodeId FromUABuiltInType( 
   UABuiltInType builtInType
)

[NotNull()]
public:
static UANodeId^ FromUABuiltInType( 
   UABuiltInType builtInType
)

Parameters

builtInType: The OPC UA built-in type to be converted.

Return Value

Returns the OPC UA data type Id (a UANodeId) that represents the OPC UA built-in type .

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.ComponentModel.InvalidEnumArgumentException	An invalid enumeration value was used. 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.

Exception

Description

System.ComponentModel.InvalidEnumArgumentException

An invalid enumeration value was used.

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
