Question

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?

Answer 1

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);     } }
