LINQ is designed not to have any side effects in general. I tend to add an
extension method to my projects that looks like:
public static void Apply<T>(this IEnumerable<T> items, Action<T> action)
{
foreach(var item in items) action(item);
}
Then you can rewrite the above as:
(from p in nameList
where p.FirstName == "Pater"
select p).Apply(p => p.FirstName = "Peter");
Or (once you start using the lambda syntax go all the way):
nameList.Where(p => p.FirstName == "Pater").Apply(p => p.FirstName =
"Peter");
