parse x12 in csharp

To parse X12 documents in C#, you can use the EdiFabric.Framework package available on NuGet. Here's an example of how to use it:

main.cs
using EdiFabric.Framework;
using EdiFabric.Framework.Readers;
using EdiFabric.Framework.Envelopes;
using EdiFabric.Core.Model.Edi.X12;

...

// Read the X12 file into a string variable
string x12String = File.ReadAllText("path/to/x12/file");

// Parse the X12 string into an interchange
var interchange = new X12Reader(x12String).ReadNextInterchange();

// Loop through the transactions in the interchange
foreach (var transactionSet in interchange.TransactionSets)
{
    // Get the transaction type
    var transactionType = transactionSet.ControlNumber;

    // Get the group of transactions
    var group = transactionSet.ParentLoop;

    // Get the functional group information 
    var functionGroup = group.ParentLoop;

    // Get the interchange header
    var interchangeHeader = interchange.Header;

    // Do something with the data
    // For example, print the transaction type to the console
    Console.WriteLine("Transaction Type: " + transactionType);
}
970 chars
33 lines

This will parse an X12 file into an Interchange object, which can then be navigated to extract the necessary information.
