Simple linq question: using linq to get an array of properties

Lets say we have a simple class

public class Foo
{
    public string FooName;
}

Now we want to do some simple work on it.

public void SomeCallerMethod(List<Foo> listOfFoos)
{
    string[] fooNames = listOfFoo. // What to do here?
}

If I even knew what method to call, I could probably find the rest of the peices.
