Dependency objects/properties from a DLL

问题

Here is the code I have :

public class MyObject : DependencyObject
{
    public int speedSimu
    {
        get { return (int)GetValue(speedSimuProperty); }
        set { SetValue(speedSimuProperty, value); }
    }

    public static readonly DependencyProperty speedSimuProperty =
        DependencyProperty.Register("speedSimu", typeof(int), typeof(MyObject), new PropertyMetadata(0));

    public int Value
    {
        get;
        set;
    }
}


public class Timer : DependencyObject
{
    public string description
    {
        get { return (string)GetValue(descriptionProperty); }
        set { SetValue(descriptionProperty, value); }
    }

    public static readonly DependencyProperty descriptionProperty =
        DependencyProperty.Register("description", typeof(string), typeof(Timer), new PropertyMetadata("This is a timer"));

}

public class AnotherClass
{

}

public class Test
{
    MyObject q1 = new MyObject();
    MyObject q2 = new MyObject();
    MyObject q3 = new MyObject();
    MyObject q4 = new MyObject();

    Timer t1 = new Timer();
    Timer t2 = new Timer();
    Timer t3 = new Timer();

    AnotherClass a1 = new AnotherClass();
    AnotherClass a2 = new AnotherClass();
    AnotherClass a3 = new AnotherClass();
}

I generate a DLL from this code and here is what I wanna do : - only get instances (== ignore all Classes but "test") : OK - filter DependencyObjects : OK - filter DependencyProperties : not OK - access to informations so I can get EXACTLY what I want (I don't want anything more) :

q1 int speedSimu : 0 q2 int speedSimu : 0 q3 int speedSimu : 0 q4 int speedSimu : 0

t1 string description : "This is a timer" t2 string description : "This is a timer"

(Note than !dependecyProperties are ignored)

The Code I have for the moment is :

var library = Assembly.LoadFrom(libraryPath);
IEnumerable<Type> types = library.GetTypes();

foreach (Type type in types)
{
     var lib = Activator.CreateInstance(type);             
     Type myType = lib.GetType();

     //This filters my Class Test. Not elegant but not my main problem at the moment.
     if (myType.BaseType.ToString() == "System.Object")
     {
         FieldInfo[] fields = type.GetFields(BindingFlags.Public | BindingFlags.Static | BindingFlags.NonPublic | BindingFlags.Instance);

         foreach (FieldInfo field in fields)
         {
             var fieldtype = field.FieldType;

             if (typeof(DependencyObject).IsAssignableFrom(fieldtype))
             {
                  //Here I am !
             }
         }
     }             
 }

The thing is that at this point, I think I'm close to the end but it seems to me like in "FieldInfos", informations about MyObject and Timer are lost (I mean properties/fields, and their values...) but I don't know how to do it in a different way... I'm really blocked here and don't know what to do next...
