EDI Flat File parsing with C#?

Initially I was thinking to use SSIS to parse an EDI file, however I've seen a few manual EDI parsers (field mapping), and would like to use automate this functionality in C#开发者_JAVA技巧.

Example EDI File:

There is EDI.Net library which is opensource and supports all three known EDI formats (X12, EDIFact, Tradacoms). In your case for X12 you need to provide a custom implementation of the IEdiGrammar with the following presets.

public class EDI_X12Grammar : IEdiGrammar
{
...
}

var grammar = new EDI_X12Grammar() 
       {
            ComponentDataElementSeparator = new[] { '>' },
            DataElementSeparator = new[] { '*' },
            DecimalMark = null,
            ReleaseCharacter = null,
            Reserved = new char[0],
            SegmentTerminator = '~',
            ServiceStringAdviceTag = null,
            InterchangeHeaderTag = "ISA",
            FunctionalGroupHeaderTag = "GS",
            MessageHeaderTag = "ST",
            MessageTrailerTag = "SE",
            FunctionalGroupTrailerTag = "GE",
            InterchangeTrailerTag = "IEA",
        };

Disclaimer I wrote the library.

Have you seen http://www.codeproject.com/KB/XML/edix.aspx

This is for X12 and worked pretty well for my uses:

It's command line, and just outputs an XML file for your EDI file.

You could possibly adapt it for your purposes.

I'm not familiar with the EDI file format, but would either of these help:

• http://sourceforge.net/projects/edival/

I am not sure if you are open to commercial tools, but I am throwing this link out here just in case. It might help somebody. Disclaimer: I am not connected in any way to this provider.
