Exporting or importing EDI to or from XML

Converting EDI to XML is seamless by using .NET XML Serializer. All EDI templates are marked for serialization.

Export EDI to XML

//  Read EDI file
List ediItems;
using (var ediReader = new X12Reader(ediStream, factory))
    ediItems = ediReader.ReadToEnd().ToList();

//  Pull all EDI objects
var transactions = ediItems.OfType();

//  Serialize each EDI object to XML
foreach (var transaction in transactions)
    var xml = transaction.Serialize();

public static XDocument Serialize(EdiMessage instance)
{
    if (instance == null)
        throw new ArgumentNullException("instance");

    var serializer = new XmlSerializer(instance.GetType());
    using (var ms = new MemoryStream())
    {
        serializer.Serialize(ms, instance);
        ms.Position = 0;
        return XDocument.Load(ms, LoadOptions.PreserveWhitespace);
    }
}

Import EDI from XML

// Read XML string
var ediXml = XElement.Load(ediStream);

// Deserialize to EDI object
var transaction = ediXml.Deserialize();

public static T Deserialize(XElement xml)
{
    var serializer = new XmlSerializer(typeof(T));
    return (T)serializer.Deserialize(xml.CreateReader());
}
