Get family types collection as project browser

[Anonymous]

Hi.

I need to get all types as listed in the project browser.

I use the next source code:

var types = new FilteredElementCollector(document).WhereElementIsElementType().Where(e=>((ElementType)e).Category != null).ToList();

However, the returned list contains more types that the showed in the project browser (see attached images).

What filter must I use to get the same list?

Hard to say... I see no similarity or relationship at all between your two screen snapshots.

I would start out by trying to use GetFamilySymbolIds:
