code for the write part:

string sStartupPath = Application.StartupPath;
XmlTextWriter objXmlTextWriter =
new XmlTextWriter(sStartupPath + @"\selected.xml",null);
objXmlTextWriter.WriteStartElement("MySelectedValues");
objXmlTextWriter.WriteStartElement("ID1");
objXmlTextWriter.WriteString(string);
objXmlTextWriter.WriteEndElement();
objXmlTextWriter.WriteStartElement("ID2");
objXmlTextWriter.WriteString(string);
objXmlTextWriter.WriteEndElement();
objXmlTextWriter.WriteEndElement();
objXmlTextWriter.Flush();
objXmlTextWriter.Close();

and for the read part:
doca = new XPathDocument(Application.StartupPath + @"\selected.xml");
nav = doca.CreateNavigator();
expr = nav.Compile("/MySelectedValues");
iterator = nav.Select(expr);
while(iterator.MoveNext())
{
XPathNavigator nav2 = iterator.Current.Clone();
nav2.MoveToFirstChild();
string s1 = nav2.Value.ToString();
nav2.MoveToNext()
string s2 = nav2.Value.ToString;
}
