ToUANodeId Method

Converts an OPC UA security role to its OPC UA node Id.

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
<JetBrains.Annotations.CanBeNullAttribute()>
<JetBrains.Annotations.ContractAnnotationAttribute("null => null; notnull => notnull")>
Public Shared Function ToUANodeId( _
   ByVal securityRole As UASecurityRole _
) As UANodeId

'Usage
 
Dim securityRole As UASecurityRole
Dim value As UANodeId
 
value = UASecurityRole.ToUANodeId(securityRole)

[JetBrains.Annotations.CanBeNull()]
[JetBrains.Annotations.ContractAnnotation("null => null; notnull => notnull")]
public static UANodeId ToUANodeId( 
   UASecurityRole securityRole
)

[JetBrains.Annotations.CanBeNull()]
[JetBrains.Annotations.ContractAnnotation("null => null; notnull => notnull")]
public:
static UANodeId^ ToUANodeId( 
   UASecurityRole^ securityRole
)

Parameters

securityRole: The security role to convert.
The value of this parameter can be null (Nothing in Visual Basic).

Return Value

The role's node ID if the security role is not null; otherwise, null.

Because there is an implicit conversion from OpcLabs.EasyOpc.UA.AddressSpace.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 OpcLabs.EasyOpc.UA.AddressSpace.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 OpcLabs.EasyOpc.UA.AddressSpace.UANodeId has an implicit conversion to System.String, and it converts to the expanded text of the node Id (OpcLabs.EasyOpc.UA.AddressSpace.UANodeId.ExpandedText), in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use the returned OpcLabs.EasyOpc.UA.AddressSpace.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 can return null (Nothing in Visual Basic).

Remarks

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

Requirements
