R.,
You are right that such constructor does not exist. This is by design – [...] having all those combinations with and without the State in the constructor would lead to having too many overloads.
So, you need to use one of the constructors that are available, and then assign the State (or other properties that were not in the constructor) afterwards. C# (I think in Version 3.0+) also has an initializer list which can make it a bit shorter to code.

Zbynek,
Yes I’ve read all of those sections in the help file. However, I don’t see a constructor that includes a parameter for the state object. That’s where I am confused. Should I just create an instance of the UaReadArguments object and assign the AttributeId, endpointdescriptor, state, etc separately?

R.,
ReadMultipleValues (www.opclabs.com/onlinedocs/Qui... ) takes an array of UAReadArguments (www.opclabs.com/onlinedocs/Qui... ).
Each of them contains a State property (www.opclabs.com/onlinedocs/Qui... ), inherited from OperationArguments. This way, you can pass in a State for each node you want to read.

Subject: Ua ReadMultipleValues Method
Hello Zbynek,
I have [....] UA question. The ReadMultipleItems method has a State property in the ValueResult. However, I don’t see any overloads for the ReadMultipleItems method that allows you to pass in a state object. Can you clarify this for me?
Thanks,
R.
