I have a collection of objects  'clsPerson' I want to serialize..
However when I do it the XML header is witten with each object instead of just at the top.

This is the code I use to serialize
    Public Function WriteXML(ByVal oCol As Collection) As Boolean
        If String.IsNullOrEmpty(mvarFilename) Then Return False

        Dim wri As New IO.StreamWriter(mvarFilename)
        For Each oObj As Object In oCol
            oObj.XMLSerialize(wri)
        Next
        wri.Close()
    End Function

This is in my 'clsPerson' Class
    Sub XMLSerialize(ByVal sWri As IO.StreamWriter) 'ByVal mc As clsPerson)
        'Dim wri As New IO.StreamWriter("Ppopcfg.xml")
        Try
            Dim Ser As New Xml.Serialization.XmlSerializer(GetType(clsPerson))
            Ser.Serialize(sWri, Me)
        Catch ex As Exception
            Stop
        End Try
    End Sub

The XML it produced. for 3 objects in the collection
----------------------------------------------------------------------
<?xml version="1.0" encoding="utf-8"?>
<clsPerson xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <FirstName>Sunnybrook</FirstName>
  <PhoneNumber>(416) 4804846 84144</PhoneNumber>
  <Selected>true</Selected>
</clsPerson><?xml version="1.0" encoding="utf-8"?>
<clsPerson xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <FirstName>St. Johns Rehab Hospitao</FirstName>
  <PhoneNumber>(416) 226-6780</PhoneNumber>
  <Selected>true</Selected>
</clsPerson><?xml version="1.0" encoding="utf-8"?>
<clsPerson xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <FirstName>Ken</FirstName>
  <LastName>Shelson</LastName>
  <PhoneNumber>(416) 516-4509</PhoneNumber>
  <Selected>true</Selected>

Wouldn't you want to serialize your collection rather than serializing each object in the collection? That way it will create 3 clsPerson elements in the file.

Hope this link helps
