Convert XmlDocument object into an XmlNode object - C#?

How do I convert an XmlDocument to a XmlNode in C#? I need to send the entire XmlDocument object to as an input parameter to a .NET web service.

A XmlDocument is a XmlNode, so you can just pass the document object.

Or you could send its DocumentElement, or any Node returned from an XPath query.

XmlDocument doc = null;
XmlNode node = doc;

XmlNode node = doc.DocumentElement;

XmlNode node = doc.SelectSingleNode("/foo/bar");

No casting or converting is needed unless you need to disambiguate XmlNode from XmlDocument for a method with overloads for both parameter types. If this is the case, use either of the cast or as operators.

An XmlDocument is derived from XmlNode, but you could also send the XmlDocument.DocumentElement which is an XmlElement but ultimately derived from XmlNode. You might need to check in XmlDocument.DocumentElement == null.

If you need to refer to it explicitly as an XmlNode use "as":

XmlDocument doc = ...

XmlNode node = doc as XmlNode;
