ForEach

[shapper]

Hello,

I got the following code from an online example:

public static void Repeater<T>(this HtmlHelper html,
IEnumerable<T> items, string className, string classNameAlt, Action<T,
string> render) {
int i = 0;
items.ForEach(item => {
render(item, (i++ % 2 == 0) ? className: classNameAlt
});
}

ForEach is not recognized.
I imported System, System.Collections, System.Collections.Generic,
System.Linq, ...

Am I missing something?

Thanks,
Miguel

List<T> has a ForEach method so you could use
items.ToList().ForEach(...)

What online example?

This one:

There's no IEnumerable<T>.ForEach() method, in the interface or as an  
extension method.

Either you copied the example wrong, or the example itself is wrong.

I didn't copied it wrong and it is strange that it is wrong because it
is from one of the Microsoft ASP.NET MVC team.

This is why I though I was missing something ...

Pete,

And that is what I have against for the programmer clever extension methods
(which is often only for him to proof how clever he is).

As soon as a program needs maintenance even the original programmer does
often not know anymore what clever extensions he has made.

This does not mean that I am against any usable method, however, keep always
maintenance in mind.

Don't understand me wrong, I write to that
