first of all, do not use object[]s. generics should be your first choice when applicable.

If you use linq to sql, you can select values from DataContext [^] like :

var level0 = dataContext.Menu_masters.ToList();
var level1 = dataContext.SubmenuParent_masters.ToList();
var level2 = dataContext.Submenu_child_masters.ToList();

but there exists better. If you mean by "menu" as MainMenu[^],
then you can store all your menu items in one table with foreign key values. you can use this table to create your menu.
