Why is my (Type).GetFields(BindingFlags.Instance | BindingFlags.Public) not working?

My code can see the NonPublic members, but not the Public ones. (???)
Full sample code below.
FieldInfo[] publicFieldInfos = t.GetFields(BindingFlags.Instance | BindingFlags.Public);
is returning nothing.
Note, I'm trying to get at the properties on the abstract class as well as the 1 concrete class.
(And read the attributes as well).
I'm going bonkers on this one....the msdn example works with the 2 flags (BindingFlags.Instance | BindingFlags.Public).....but my mini inheritance example below is not.
THANKS in advance.
/////////////START CODE
private void RunTest1()
{
try
{
textBox1.Text = string.Empty;
Type t = typeof(MyInheritedClass);
//Look at the BindingFlags *** NonPublic ***
int fieldCount = 0;
while (null != t)
{
fieldCount += t.GetFields(BindingFlags.Instance |
BindingFlags.NonPublic).Length;
FieldInfo[] nonPublicFieldInfos = t.GetFields(BindingFlags.Instance |
BindingFlags.NonPublic);
foreach (FieldInfo field in nonPublicFieldInfos)
{
if (null != field)
{
Console.WriteLine(field.Name);
}
}
t = t.BaseType;
}
Console.WriteLine("\n\r------------------\n\r");
//Look at the BindingFlags *** Public ***
t = typeof(MyInheritedClass);
FieldInfo[] publicFieldInfos = t.GetFields(BindingFlags.Instance |
BindingFlags.Public);
foreach (FieldInfo field in publicFieldInfos)
{
if (null != field)
{
Console.WriteLine(field.Name);
object[] attributes = field.GetCustomAttributes(t, true);
if (attributes != null && attributes.Length > 0)
{
foreach (Attribute att in attributes)
{
Console.WriteLine(att.GetType().Name);
}
