Parameters

clientNodeRegistration
The client node registration object that will perform the operation.
endpointDescriptor
The endpoint descriptor of the server on which the node reside.
nodeDescriptor
Descriptor of the node that should be registered.

Return Value

Exceptions
ExceptionDescription

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

If you have more nodes to register, it is strongly recommended that you use the OpcLabs.EasyOpc.UA.Services.IEasyUAClientNodeRegistration.RegisterMultipleNodes method instead, for performance reasons.

The method may perform the registration asynchronously.

Requirements

Target Platforms: .NET Framework: Windows 10 (selected versions), Windows 11 (selected versions), Windows Server 2016, Windows Server 2022; .NET: Linux, macOS, Microsoft Windows
