extract values out of object

Hello, dear reader.
I am trying to find out relations between EF Database objects
This is the function to fulfill that task:

private object getCollectionReference(object EFtable, string navigationproperty)
        {
            object collectionreference = new object();
            //now try to query the table
            try
            {
                DbEntityEntry db = ce.Entry(EFtable);
                //query collections of referenced tables
                collectionreference = db
                    .Collection(navigationproperty)
                    .Query()
                    .AsQueryable();
            }
            catch (Exception e)
            {
                //query single referenced table
                DbEntityEntry db = ce.Entry(EFtable);
                collectionreference = db
                    .Reference(navigationproperty)
                    .Query()
                    .AsQueryable();
            }
            return collectionreference;
        }

That works pretty well until it comes to casting... :-(
The object EFtable can be any Entity in our database.
Is there any opportunity to cast it back into the desired "EF Object" for further processing it?
I read dozens of articles about solving that with Reflections, here is what I´ve done so far:

     //get the referenced table[s]
object referenceLogAction4 = getCollectionReference(us, "Data_Subjects");
     //get the type
Type ref4 = referenceLogAction4.GetType();
  //load all properties
IList<PropertyInfo> pops = new List<PropertyInfo>(ref4.GetProperties());
List<object> lobj = new List<object>();
foreach (PropertyInfo pop in pops)
{
      object popvalue = pop.GetValue(referenceLogAction4, null);
      lobj.Add(popvalue);
}
//try loading fields
IList<FieldInfo> fies = new List<FieldInfo>(ref4.GetFields());
List<object> lfie = new List<object>();
foreach (FieldInfo fie in fies)
{
    object fiesvalue = fie.GetValue(referenceLogAction4);
    lfie.Add(fiesvalue);
    
}

neither Propertyinfo nor Fieldinfo seems to be what I want; the Fieldinfo part returns zero Fieldinfos, the Propertyinfo values are:

"it"
"Transformed SQL Statement"
[System.Data.Entity.Core.Objects.ObjectContext]
AppendOnly
true
[System.Data.Entity.Core.Objects.ObjectParameterCollection]
true

Seems to me that these are the standard properties of type object...

I also tried casting it via

ToType<T>(this object obj, T type) where T : class
...

but to no avail...

so, to put long things short:

does anybody know, what I need to do to cast the object to my desired EF entity object?

Thanks a lot in advance,
Clodetta
