I don't think LINQ is meant to do this. LINQ is "Language Integrated Query", a query being something of a question used to select, modify or delete data. The performance gain, if any, will be slight. I actually think it might slow it down. But if you must... (Doing this from memory)

List<MyStyle> styles = new List<MyStyle>();
styles.AddRange((MyStyle[])(from item in items select GetMyStyle(item.style)).ToArray());

Off the top of my head:

List<MyStyle> styles = items.Select(item => GetMyStyle(item.style)).ToList();

Isn't that a Lambda?

It's LINQ using a Lambda expression, as a lot of LINQ does.

I think you may use its constructor to add values in it. List<MyStyle> l = new List<MyStyle>(items.Select(s => GetMyStyle(s.style))); Thanks :)
