LINQ equivalent of foreach for IEnumerable<T>

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

IEnumerable<Item> items = GetItems();
items.ForEach(i => i.DoStuff());

What is the real syntax?

Solution

  • There is no ForEach extension for IEnumerable; only for List<T>. So you could do

    items.ToList().ForEach(i => i.DoStuff());

    Alternatively, write your own ForEach extension method:

    public static void ForEach<T>(this IEnumerable<T> enumeration, Action<T> action)
{
    foreach(T item in enumeration)
    {
        action(item);
    }
}
