[jmyr]

Hi All im trying to get all element types like in dynamo but using c# but no success. Please see below.

i tried below code but i get different result

            List<ElementType> elementTypes = new FilteredElementCollector(_doc)
                .OfClass(typeof(ElementType))
                .WhereElementIsElementType()
                .Select(x => (ElementType)x)
                .ToList();

Probably the list you show in the image is using a different vocabulary than the Revit API.

Maybe what you really are after are categories, not element types?
