Convert a list of objects to an array of one of the object's properties

Say I have the following class:

public class ConfigItemType
{
    public string Name { get; set; }
    public double SomeOtherThing { get; set; }
}

and then I make a list of the following classes (List<ConfigItemType> MyList)

Now I have a method with the following signature:

void AggregateValues(string someUnrelatedValue, params string[] listGoesHere)

How can I fit MyList in to the listGoesHere using the value in ConfigItemType.Name as the params string array?

I am fairly sure that Linq can do this.... but MyList does not have a select method on it (which is what I would have used).
