Abstract classes, static field values and reflection

[Torben K. Jensen]

I've hit the wall with this one:

Using System.Reflection.FieldInfo, I can retrieve the values of any field from an instantiated class and constant fields from abstract classes.
However, it seems impossible to retrieve the values of static fields in an abstract class. Is there any way to do this?

My concrete goal is to retrieve a list containing all static string values in System.Windows.Forms.DataFormats, so I can make a S.W.F.Design.ComponentEditorPage containing a CheckBox for each format used in drag&drop operations.

Any hints are greatly appreciated.

I found the solution:
FieldInfo[] info = typeof(DataFormats).GetFields();

foreach (FieldInfo field in info) {
listBox1.Items.Add(field.GetValue(null));
}
I had no idea you could pass a null value to FieldInfo.GetValue() to retrieve the values of static fields, but apparently you can. Whowouldathunk.
