using System;
using System.Reflection;

public class A
         public static int X = 0;

public class B : A
         static void Main ()
                 BindingFlags bf = BindingFlags.Public |
                         BindingFlags.Static |

                 foreach (FieldInfo fi in typeof (B).GetFields (bf)) {
                         fi.SetValue (null, 42);
                         Console.WriteLine (X == 42);
