What have you tried? Opening a file and getting all its contents is one of the most fundamental operations... — walther

Why do you need to store entire XML file in a string ? Is the question like - Reading the XML file, changing element / attribute and saving it back ?. If yes, then there are enormous amount of samples available. Just search it on. Something like XDocument.Load(@"C:\MyFile.xml"); — Angshuman Agarwal

Reading an XML file into a string is simple:

string xml = File.ReadAllText(fileName);

The to access the content, you would read it into an XmlDocument:

XmlDocument doc = new XmlDocument();
doc.LoadXml(xml);

using System.Xml.Linq;

// load the file
            var xDocument = XDocument.Load(@"C:\MyFile.xml");
// convert the xml into string (did not get why do you want to do this)
            string xml = xDocument.ToString();

Now, using xDocument, you can manipulate the XML & save it back -

           xDocument.Save(@"C:\MyFile.xml");

Why don't you directly read XML to XmlDocument

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(xmlFilePath);

When you need XML as string then use XmlNode.OuterXml property.
