Linq style “For Each” [duplicate]

Answer 1

There isn't anything built-in, but you can easily create your own extension method to do it:

public static void ForEach(this IEnumerable source, Action action)
{
    if (source == null) throw new ArgumentNullException("source");
    if (action == null) throw new ArgumentNullException("action");

    foreach (T item in source)
    {
        action(item);
    }
}
