问题:

We have data stored in a database and we need to create an ANSI 837 file from this data. Are there any open source frameworks available to do this in .NET?

回答1:

OopFactory X12 parser is an open source C# implementation of an X12 parser.
EDI notepad (free version) may also help with this.

回答2:

Why not use a standard mapper instead of trying to code that beast? There's a lot of minefields there (ISA/GS enveloping, control numbers, HL segments, segment looping) that EDI translators already have built-in dictionaries to use.

While not open source, there is a company out there who provides programming tools that might help your cause: http://www.edidev.com/ (more specifically: http://www.edidev.com/edidev_hipaa_support.htm).

http://chiapas.sourceforge.net

It can be executed from the command line or integrated as a C# component. It has a 76 page PDF manual which goes over many of the features, check it out.

not .net, but is open source: http://bots.sourceforge.net

回答5:

Check out the open source .NET X12parser. It's already got fairly robust support for the X12 healthcare formats (including 837). You'll just supply the 837 data in a XML format and it will create a valid X12 file.
