Object reference not set to an instance of an object

[Andrew]

Hi all,

//msg has been assigned as type
NHapi.Base.Model.GenericMessage.V23
//NHapi.Model.V23.Message.ORU_R01

ORU_R01 ORUR01 = msg as ORU_R01;

I've got the error coz ORUR01 is always null, because I can't convert msg to
a different type ie to type ORU_R01

How do I do this ?

Thanks

regards,
Andrew

Do what, exactly? You've not really given enough context to know what
the situation is or what you're really trying to do.

Do the classes "NHapi.Base.Model.GenericMessage.V23" and
"NHapi.Model.V23.Message.ORU_R01" have any relationship to each other? They
aren't in the same namespace.
