foreach vs someList.ForEach(){}

There are apparently many ways to iterate over a collection. Curious if there are any differences, or why you’d use one way over the other.

First type:

List<string> someList = <some way to init>
foreach(string s in someList) {
   <process the string>
}

Other Way:

List<string> someList = <some way to init>
someList.ForEach(delegate(string s) {
    <process the string>
});

I suppose off the top of my head, that instead of the anonymous delegate I use above, you’d have a reusable delegate you could specify…
