XML variable fil

Gem dine data i en instans af en dertil oprettet klasse og gem/hent med
XmlSerializer Serialize/Deserialize

Er der mulighed for at du kan give mig noget kodeeksempel jeg kan arbejde med ?

Imports System
Imports System.IO
Imports System.Xml.Serialization

Public Structure Test
  Public a As Integer
  Public b As Double
  Public c As String
End Structure

Class MainClass
  Public Shared Sub Main(ByVal args As String())
      Dim tst As Test
      tst.a = 123
      tst.b = 123.456
      tst.c = "ABC"
      Dim ser As XmlSerializer = New XmlSerializer(GetType(Test))
      Dim sw As StreamWriter = New StreamWriter("C:\test.xml")
      ser.Serialize(sw, tst)
      sw.Close
      Dim sr As StreamReader = New StreamReader("C:\test.xml")
      Dim tst2 As Test = CType(ser.Deserialize(sr), Test)
      sr.Close
      Console.WriteLine(tst2.a & " " & tst2.b & " " & tst2.c)
  End Sub
End Class

OK ?
