OpenOrCreateStream Method

Opens an existing OPC UA file, or creates a new OPC UA file if one does not exist, and returns a System.IO.Stream to access the file data.

If the file already exists, the method opens it. If the file does not exist, the method creates a new file. In both cases, the method returns a System.IO.Stream object that can be used to access the file data.
