UANodeId Constructor(String,Object)

Initializes a new instance of the class, specifying the namespace URI string, and identifier.

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
Public Function New( _
   ByVal namespaceUriString As String, _
   ByVal identifier As Object _
)

'Usage
 
Dim namespaceUriString As String
Dim identifier As Object
 
Dim instance As New UANodeId(namespaceUriString, identifier)

public UANodeId( 
   string namespaceUriString,
   object identifier
)

public:
UANodeId( 
   String^ namespaceUriString,
   Object^ identifier
)

Parameters

namespaceUriString

Namespace URI string. Determines the namespace of the node Id.

The value represents an OPC UA namespace URI string. 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.

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

identifier

Identifier value, either numeric, string, GUID, opaque, or none.

The value of this parameter can be null (Nothing in Visual Basic).

Exceptions

Exception Description

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.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.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.
