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

If you want to act as the enumeration rolls you should yield each item.

public static class EnumerableExtensions
{
    public static IEnumerable ForEach(this IEnumerable enumeration, Action action)
    {
        foreach (var item in enumeration)
        {
            action(item);
            yield return item;
        }
    }
}
