How come when I use "DeserializeXmlNode" and my JSON gets converted to an XML document then convert my XML document into a string like this

   string strXML = "";
   StringWriter writer = new StringWriter();
   xmlDoc.Save(writer);
   strXML = writer.ToString();

It includes 

<?xml version="1.0" encoding="utf-16"?>

I did not add this, how do I remove it?

Use XmlWriter with StringBuilder instead of StringWriter

 var strXML = "";
 var writer = new StringBuilder();   
 var settings = new System.Xml.XmlWriterSettings() { OmitXmlDeclaration = true};
 var xmlWriter = System.Xml.XmlWriter.Create(strXML, settings);   
 xmlDoc.Save(xmlWriter);
 strXML = writer.ToString();

an XML without that line is not a valid XML file!

that line is called the XML Declaration

as an example, check out the OData XML from Netflix on Catalog Titles, can you see that first line?

http://odata.netflix.com/Catalog/Titles

But I dont need it to be valid, in a web service API. :) – 001 May 24 '11 at 12:41
you should always use that line, or you will not be able to parse it correctly, specially if you now, or in the future use some encoding for special char like ö or ü etc... – balexandre May 24 '11 at 12:53
