Use this method to convert values read from the Fields property into appropriate objects such as a SimpleList object or a VariantArray. If the encoding in the string contained in the Fields property indicates a SimpleList object, then a SimpleList object is returned. If the encoding indicates a VariantArray, then a VariantArray is returned. If no collection object is indicated, then the method returns the original encoded input string.

Parameters
