When get access to property "Name" of ElementType, an AttributeError raised.

[Alvislakewang]

Hello,
I am writing a script to list all types exist in the project for specific categories, but whenever I try to get access to the property Name of ElementType Object, an AttributeError will be raised.

Code is as follow:

fc = BuiltInCategory.OST_StructuralFoundation
types = FilteredElementCollector(doc).OfCategory(fc).WhereElementIsElementType().ToElements()
type_names = []
for _type in types:
t_name = _type.Name
type_names.append(t_name)

Error information:

ElementType.Name is Write-Only (it only has set in API docs). If you want to get its name, please get its Parameter TypeName's value

Ya that's one of the known issues with IronPython. It specifically happens on the Name property. Use the workaround shown below to read the value:

DB.ElementType.Name.GetValue(_type)
