XDocument Constructor (XDeclaration, Object)
Assembly: System.Xml.Linq (in System.Xml.Linq.dll)
There are not many scenarios that require you to create an XDocument. Instead, you can usually create your XML trees with an XElement root node. Unless you have a specific requirement to create a document (for example, because you have to create processing instructions and comments at the top level, or you have to support document types), it is often more convenient to use XElement as your root node.
