Serj-Tm answered adequately but Activator can do it too:

var foo = (Foo) Activator.CreateInstance(typeof(Foo), 
               BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance, 
               null, 
               new object[] { 2.0 }, 
               CultureInfo.InvariantCulture);
