In the quest to design a way to use LINQ over XML data, Microsoft needed to create a new set of classes that would simplify the task, so it created the XDocument classes: XElement, XAttribute, XNamespace, XDirective, and more.To use these classes, you must add a reference to the System.Xml.Linq.dll assembly, and then you can add an imports (C# using) System.

The formed XML file should be converted into the XML document for this we will use. Keep the retrieved data in XElement, then make the necessary changes and finally apply the save operation on the XDocument object class. Notice that, we don't need to reassign the modified XElement object as its being referenced internally from the XDocument object and apply the necessary changes while saving XElement root = new XElement(Record); The string Record is automatically converted to an XName object and this is used to set the Name property of the new XElement. An XName is used instead of a simple string because XML names have some additional behaviour because of namespaces - more later
