I have the following classes:

public class MyEventArgs : EventArgs
{
    public object State;

    public MyEventArgs (object state)
    {
        this.State = state;
    }

}

public class MyClass
{
     // ...

     public List<string> ErrorMessages 
     {
          get
          {
               return errorMessages;
          }
      }
}

When I raise my event, I set 'State' of the MyEventArgs object to an object of type MyClass. I'm trying to retrieve ErrorMessages by reflection in my event handler:

 public static void OnEventEnded(object sender, EventArgs args)
 {
      Type type = args.GetType();
      FieldInfo stateInfo = type.GetField("State");
      PropertyInfo errorMessagesInfo = stateInfo.FieldType.GetProperty("ErrorMessages");

      object errorMessages = errorMessagesInfo.GetValue(null, null);

  }

But this returns errorMessagesInfo as null (even though stateInfo is not null). Is it possible to retrieve ErrorMessages ?

Thank you
