LINQ equivalent of foreach for IEnumerable

Question

I\'d like to do the equivalent of the following in LINQ, but I can\'t figure out how:

IEnumerable items = GetItems();
items.ForEach(i => i.DoS         


        

Answer 1

You could use the FirstOrDefault() extension, which is available for IEnumerable. By returning false from the predicate, it will be run for each element but will not care that it doesn't actually find a match. This will avoid the ToList() overhead.

IEnumerable items = GetItems();
items.FirstOrDefault(i => { i.DoStuff(); return false; });
