Xmldocument represents an entire XML loaded into memory, while Xmlwriter is an object that assists in writing XML into a stream.

Xmldocument

If you want to manipulate an XML, for example, load it from a file, change some part of its structure, and then save it, then I would use Xmldocument for that. With it is possible locate the elements using Xpath, which greatly facilitates manipulation.

Xdocument

This class and its related ones are part of . Net from version 3.5 onwards, much easier to work with than with Xmldocument and related. If you want to create applications without taking the previous versions of . net then this is the recommended way.

To create an XML structure, you only need a statement, instead of inserting nodes:

var xdocument = new XDocument(
    new XElement("elementoRaiz",
        new XAttribute("atributo1", "valor"),
        new XElement("elementoFilho", "texto do elemento filho"),
        new XElement("elementoFilho2", "texto do elemento filho 2")
    ));

Xmlwriter

If you just want to write an Xml in a file, for example, reading data from any source such as a database, you could use Xmlwriter to write the XML as you read the data from the database.

  • Thank you @Miguel, could you also explain about Xdocument as well ? in a brief search, Xdocument looks like the most organized and beautiful syntax, rsrsrs

Xmldocument is a more complex class than Xmlwriter, as it contains more methods for handling xml while Xmlwriter basically serves to record this xml.
