public class GetElementType : IExternalCommand

public Result Execute(ExternalCommandData commandData, ref string messages, ElementSet elements)
{
UIApplication uiApp = commandData.Application;
Document doc = uiApp.ActiveUIDocument.Document;
Selection sel = uiApp.ActiveUIDocument.Selection;

Reference refelem = sel.PickObject(ObjectType.Element, "请选择一个风管");
FamilyInstance fi = refelem.Element as FamilyInstance;

MessageBox.Show(fi.Symbol.Family.Name);//得到类型名，比如天圆地方 - 角度 -法兰
MessageBox.Show(refelem.Element.GetType().Name);//得到类型，比如风管对应Duct而弯头之类却都对应FamilyInstance
return Result.Succeeded;
