Revit 二次开发——设置内置类别在激活视图下的可见性

public static void SetCategoryHidden(Document doc, BuiltInCategory builtInCategory, bool n)
        {
            try
            {
                Categories cates = doc.Settings.Categories;
                Category cate = cates.get_Item(builtInCategory);
                doc.ActiveView.SetCategoryHidden(cate.Id, n);
            }
            catch (Exception)
            {
                TaskDialog.Show("Error", "设置类别可见性失败");
            }
        }
