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.
Answer
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.
