A while ago I wrote a suggestion on how to write an application to support multiple version of HL7 using nHapi. After some questions I received, an example application seems to be helpful. My original post seems to be a little abstract. So here's the example solution I just hacked together. Enjoy! If you have any questions, let me know!

Hi,

Thank you for your compliment! :lol:I just translated your comment from Pinyin to English. The translation is "Good thing." (Is that correct?)

Thanks again,

Hello,

Employing .Net dynamics, one can implement a factory without a naive switch implementation. For example:

IMessage message = parser.Parse(message);
dynamic o = Convert.ChangeType(mess age, message.GetType());
PL location = o.PV1.AssignedPatient Location;

The only disadvantage is that you lose compile-time checking, but this approach should drastically reduce boiler plate code.

Cheers,
Pete

Hi Slypete,

Thank you for your comment. This way will absolutely shorten the code.

There are two reasons that I didn't use .Net dynamics. The first one is that it didn't yet exist at the time (I think... maybe it did and I didn't know about it at the time). The second one is that this code is an example. Statements like dynamic sure are code optimizations. On the other hand they make the code far less comprehensible for less experienced developers. In my opinion it is better to have more code that is better readable than to have less code that isn't.

Of course if an experienced developer would take this example. .Net dynamics will shorten the code and, therefore, make it easier to maintain.

Thanks,

Division by Zero
