C#/PHP : Is there an equivalent of PHP's array_map() function in C#?

[PachiUniverse]

I've been pondering this today, and I have a nagging feeling that this is something simple to implement and I'm just way out of it today, but anyway, here it is.Instead of performing something like\[code\]// assume that I have a populated string[] myStringfor (int i = 0; i < myString.Length; i++) { myString = myString.Equals(string.Empty) ? "foo" : "bar;}\[/code\]I'd like to do something like PHP's array_map(), which (I think) would perform faster than explicit iteration.Does C# have capacity for this kind of operation?
