      Dim sw As New StreamReader("data.xml")
      Dim theWorker As employee
      theWorker = theSerializer.Deserialize(sw)
      Console.WriteLine(theWorker.first_name )
      Console.WriteLine(theWorker.last_name )
      Console.WriteLine(theWorker.title)

    End Sub
End Class
Public Class employee
   Public first_name As String
   Public last_name As String
   Public title As String
   Public Sub New()
   End Sub
   Public Sub New(ByVal first_name As String,ByVal last_name As String,ByVal title As String)
      Me.first_name = first_name
      Me.last_name = last_name
      Me.title = title

Serialize Class to xml file

Imports System.Xml.Serialization, System.IO
Public Class Tester
    Public Shared Sub Main
    
      Dim theSerializer As New XmlSerializer(GetType(employee))
      Dim SGamgee As New employee("A", "G", "C")
      Dim sw As New StreamWriter("data.xml")
      theSerializer.Serialize(sw, SGamgee)
    End Sub
End Class
Public Class employee
   Public first_name As String
   Public last_name As String
   Public title As String
   Public Sub New()
   End Sub
   Public Sub New(ByVal first_name As String,ByVal last_name As String,ByVal title As String)
      Me.first_name = first_name

XML Serialization

Imports System.IO
Imports System.Xml.Serialization
Public Class Point
  Public X As Integer
  Public Y As Integer
  Public Overrides Function ToString() As String
    Return "(" & X & "," & Y & ")"
  End Function 
End Class
Module Test
  Sub Main()
    Dim P1 As New Point()
    P1.X = 6
    P1.Y = 4
    SaveToFile(P1)
    Dim P2 As Point = RetrieveFromFile()
    Console.WriteLine(P2.ToString())
  End Sub
  Sub SaveToFile(P as Point)
    Dim Serializer As New XmlSerializer(GetType(Point))
    Dim Writer As StreamWriter = New StreamWriter("point.xml") 
    Serializer.Serialize(Writer, P) 
    Writer.Close()
  End Sub
  Function RetrieveFromFile() As Point
    Dim ReturnObject As Point
    Dim Serializer As New XmlSerializer(GetType(Point)) 
    Dim FS As FileStream = New FileStream("point.xml", FileMode.Open) 
    ReturnObject = CType(Serializer.Deserialize(FS), Point) 
    FS.Close()
    Return ReturnObject
  End Function
End Module
