NHAPI C# 3.5 parsing orm_001 2.3

Question

I am having trouble putting a structure on this message. It is an order message. When it casts it stays null so orm001 is always null. I used some other hl7 types and it went in ok. I and thinking it may be the OBR line but it still does the same thing when we take it out.

 static void Main(string[] args)
    {
        string message =

        Console.ReadLine();

        }
    }

在ORM_O01中 ，不允许重复IN1 ，不允许OBR
