    /// <summary>
    /// Create file code
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    private void button1_Click(object sender, EventArgs e)
    {
        XmlTextWriter newXmlFile = new XmlTextWriter(filename,System.Text.Encoding.Default);    
        newXmlFile.WriteStartDocument();            
        newXmlFile.WriteStartElement("Begin","");
        newXmlFile.WriteStartElement("One","");
        newXmlFile.WriteFullEndElement();
        newXmlFile.WriteEndElement();

Look at Linq to XML and the System.Xml namespace.

Like Oded says: Linq to XML should get you there...

These classes are the important ones:

• XDocument
  • `var doc = XDocument.Load("myfilepath")
• XElement
• XAttribute
