Getproperties in the result of reflection invoke

I have following code in reflection was trying to get the PropertyInfo and value returned

EDIT: GetObject has been used to get the object of already initialized value .

EDIT: missed the line

object valDefault =  mInfo.Invoke(objNewcompact, objParams);
if (valDefault.GetType().IsGenericType && valDefault.GetType().GetGenericTypeDefinition() == typeof(List<>))
{
    PropertyInfo[] propertyInfo = valDefault.GetType().UnderlyingSystemType.GetGenericArguments()[0].GetProperties();

    //Activator.GetObject(valDefault.GetType().UnderlyingSystemType.GetGenericArguments()[0].UnderlyingSystemType, "http://localhost:8000/" + valDefault.GetType().UnderlyingSystemType.GetGenericArguments()[0].UnderlyingSystemType);
    string ResultString = string.Empty;
    object ooo = Activator.GetObject(valDefault.GetType().UnderlyingSystemType.GetGenericArguments()[0].UnderlyingSystemType, null);

    for (int j = 0; j < propertyInfo.Count(); j++)
    {
        ResultString += propertyInfo[j].GetValue(valDefault.GetType().UnderlyingSystemType.GetGenericArguments()[0].UnderlyingSystemType, null);
    }

I know there has been a confusing variable name. All I need value from the property from that PropertyInfo.
