Lets say I have an XmlNode that validates against some schema. I also have
a class that was generated by the xsd tool using said schema.

What is the best way to get from an XmlNode to an instance of the class?

System.Xml.Serialization.XmlSerializer.Deserialize()
accepts an XmlReader.

and you can create a System.Xml.XmlNodeReader from a System.Xml.XmlNode

Thanks Dino,

Going the other way (I know I didn't mention this) doesn't seem as elegant.

Is there a better way than this?

// slightly paraphrased
Stream stream = new MemoryStream();
new XmlSerializer( typeof(MyObject) ).Serialize( stream, myObject );
stream.Seek( 0, SeekOrigin.Begin );
XmlDocument doc = new XmlDocument();
doc.Load( stream );
return doc.DocumentElement;

Thanks again,
Brad
