Question

First, I know there are methods off of the generic List<> class already in the framework do iterate over the List<>.

But as an example, what is the correct syntax to write a ForEach method to iterate over each object of a List<>, and do a Console.WriteLine(object.ToString()) on each object. Something that takes the List<> as the first argument and the lambda expression as the second argument.

Most of the examples I have seen are done as extension methods or involve LINQ. I’m looking for a plain-old method example.

Answer 1

public void Each<T>(IEnumerable<T> items, Action<T> action) {     foreach (var item in items)         action(item); } 

… and call it thusly:

Each(myList, i => Console.WriteLine(i));
