Can a combobox's entries be saved in a .xml file

I have searched and searched for days but for the life of me I can not find information on saving the contents/entries of a combobox to a .xml file. I am using vb.net 2010 framework 4. on Windows XP SP3. I need to learn how to loop through the combobox and then save all the entries probably no more the 20 to my .xml file. I also need of course, to retrieve the information and put it back into the combo box. I would like to use xmlwriter and xmlreader since I started with them. I really need to see an example and as much information available of how it works. Thank you in advance.

        If IO.File.Exists(VarXml.ToString + ".xml") = False Then
            Dim settings As New XmlWriterSettings()
            settings.Indent = True

            Dim XmlWrt As XmlWriter = XmlWriter.Create(VarXml.ToString, settings)

            With XmlWrt

                .WriteStartDocument()
                .WriteComment("ADES Database.")
                .WriteStartElement("Data")
                .WriteStartElement("Person")
 
                .WriteStartElement("ClientName")
                .WriteString(ClientName.ToString)
                .WriteEndElement()

                .WriteStartElement("EvaluationDate")
                .WriteString(StartDate.ToString)
                .WriteEndElement()

                .WriteStartElement("FirstName")
                .WriteString(Fname.ToString)
                .WriteEndElement()

                .WriteStartElement("MiddleName")
                .WriteString(Mname.ToString)
                .WriteEndElement()

                .WriteStartElement("LastName")
                .WriteString(Lname.ToString)
                .WriteEndElement()
                .WriteEndElement()
                .WriteEndDocument()
                .Close()

            End With
