Parameters
- propertyId
- A numerical Id of the property whose name should be determined.
- serverClsid
- A CLSID of the OPC server for which the property name should be obtained. This is used for properties that are server-specific. For standard properties, the method does not use this parameter and it can be passed in as Guid.Empty.
Return Value
Returns a string identifier of the property, for pre-defined properties. An empty string is returned if the property is not known.
