why .net c# lack of "EACH" [duplicate]

Question

Possible Duplicate:
is there a .Each() (or .ForEach() ) iterator in the .Net standard library?

Maybe I am wrong, but I don't see the "EACH" function in .net (3.0)?

We can

IEnumerable<T>.Select().Where().First().Any()

Why don't we have

IEnumberable<T>.Each(Action<T> action)?

So instead of 2 lines: Foreach(T t in list) action(t);

we can just call list.Each((t)=>{blah;blah;})?

Is there a concern for performance?

It was made this way, since none of the extention methods on IEnumerable was supposed to have any side effects, and a ForEach would have side effects as it's primary objective.

It was deemed that a foreach loop is not much more verbose to write out.
