each is an iterator. Foreach loops works on list. You're asking if it's possible to cut a piece of wood with a screwdriver. A foreach loop (whether using the for or foreach keyword) calls the list building expression once, and iterates over the resulting list. A C-style for loop (whether using the for or foreach keyword) could, since it's really a while loop with bells and whistles. Since you can probably cut a piece of wood with a screwdriver if you tried hard enough, But using the appropriate tool is better. or
