Accessing Node with the value as an array|OPC UA Implementation: Stacks, Tools, and Samples|Forum|OPC Foundation

I am trying to access the value of a Node that is an array. Im not sure how to properly handle this value or access the index of the array. I am currently getting the value with this code:

ReadNode(nodeId);

The type is DataValue but I am not able to iterate over this value. How can I change to a collection to access the elements within the array?
