1Where do you get the byte array from? Do you know the encoding used?R. Martinho Fernandes– R. Martinho Fernandes2011-04-07 13:51:19 +00:00Commented Apr 7, 2011 at 13:51

I meant the character encoding of the XML document.R. Martinho Fernandes– R. Martinho Fernandes2011-04-07 13:56:04 +00:00Commented Apr 7, 2011 at 13:56

XmlDocument doc = new XmlDocument();
string xml = Encoding.UTF8.GetString(buffer);
doc.LoadXml(xml);
OR
XmlDocument doc = new XmlDocument();
MemoryStream ms = new MemoryStream(buffer);
doc.Load(ms);
This assumes your data has UTF8 encoding which is the usual for XML. Also buffer here is the byte array.

Good answer, although the MemoryStream is IDisposable so don't forget to wrap it in a using block! :)

because of a byte order mark (BOM) I found this overload more useful (thanks Jon Skeet)
MemoryStream ms = new MemoryStream(buffer, true);Assuming your xml is in the default 'UTF8' encoding., you could do something like this;
string xml = System.Text.UTF8Encoding.UTF8.GetString(bytes);
System.Xml.XmlDocument xdoc = new System.Xml.XmlDocument().LoadXml(xml);
Or this;
XmlDocument doc = new XmlDocument();
using (MemoryStream ms = new MemoryStream(buffer))
{
doc.Load(ms);
}

Based on the Encoding, you can do
string xmlString = System.Text.UTF8Encoding.UTF8.GetString(bytes);
and use the string
XmlTextReader reader = new XmlTextReader(new StringReader(xmlString));

Ooops... GetBytes takes a string and gives an array of bytes. GetString takes an array of bytes and gives a string. FTFY.
Take a look at the System.Text.Encoding.UTF8 class. It should let you convert youre byte array into a UTF8 string.

See XML Encoding Defaults page here. UTF8 is the correct assumption is most cases.

Still, I think you should have a note about it on your answer.
