I found the solution:
FilteredElementCollector viewCollector = new FilteredElementCollector(doc);
viewCollector.OfClass(typeof(FilterElement));
the FilterElements in the collection are the ones in the dialog describe in my question.
题
Does anybody know how to access and add the filters from the filters tab in the Visibilty Graphics from the Revit API in C#? I am using versie 2014 of the API. In the second screenshot the list is empty but in my revit project it is filled with filters.
