Question

I have a class that is marked with DataContract attributes and I would like to create an XDocument from objects of that class. Whats the best way of doing this?

I can do it by going via an XmlDocument but this seems like an unnecessary step.

Answer 1

You can create an XmlWriter directly into the XDocument:

XDocument doc = new XDocument();
using (var writer = doc.CreateWriter())
{
    // write xml into the writer
    var serializer = new DataContractSerializer(objectToSerialize.GetType());
    serializer.WriteObject(writer, objectToSerialize);
}
Console.WriteLine(doc.ToString());
