I need to to build an app that will parse HL7 messages with C#.Net. I haven't been able to find many options, however, nhapi is one of the few and comes highly rated, but without any documentation (even on their website/source forge). So I am new to HL7 and and creating TCP listeners for the messages. I can not find much documentation on the subject anywhere, just a lot of people yelling that there isn't any. I am looking for a simple example that will take the HL7 messages from whatever port is assigned, parse it so that I can put into a file, XML, or a SQL table.
