GetValue on static field inside nested classes.

Question

Hi...

I have the following class declared. I need to retreive the class structure and the static values without instanciate it.

public class MyClass()
{
    public static string field = "Value";

    public class nestedClass()
    {
        public static string nestedField = "NestedValue";
    }
}

I've successfuly used GetFields and GetNestedType to recover the class structure and GetValue(null) works fine on field, but not on nestedField. Let me sample:

var fi = typeof(MyClass).GetField("field", BindingFlags.Public | BindingFlags.Static);
var nt = typeof(MyClass).GetNestedType("nestedClass", BindingFlags.Public);
var nfi = nt.GetField("nestedField", BindingFlags.Public | BindingFlags.Static);
// All the above references are detected correctly
var value = fi.GetValue(null); // until here everything works fine. value == "Value"
var nestedValue = nfi.GetValue(null); // this one does not work!! 

Anyone knows why the last line does not work and how to work around? Thanks.
