If you have an official schema, you can use the XmlSerializer. Otherwise it is best to use the XmlDocument, XmlNode, XmlElement etc classes.

Otherwise it could also depend on what you are using the xml for, i.e. marking up some document, representing objects etc.

If it is a really huge XML which cannot fit into memory you should use XmlReader/XmlWriter. If not LINQ to XML is very easy to use. If you don't have .NET 3.5 you could use XmlDocument.

Here's an example of removing a node:

using System.Xml.Linq;
using System.Xml.XPath;

var doc = XElement.Load("test.xml");
doc.XPathSelectElement("//customer").Remove();
doc.Save("test.xml");
