xml and serilisation

[spike232]

i have the following code that works for binary serilisation:

Private Sub binarysave(ByRef hold As Object, ByVal filename As String)
        Dim s As Stream = New FileStream(filename, FileMode.Create)
        Dim b As BinaryFormatter = New BinaryFormatter()

        b.Serialize(s, hold)
        s.Close()
    End Sub

however the folloing to do the same but using xml insted does not work, any ideas??

    Private Sub xmlsave(ByRef hold As settings, ByVal filename As String)
        Dim s As Stream = New FileStream(filename, FileMode.Create)
       Dim x As XmlSerializer = New XmlSerializer(GetType(settings))

        x.Serialize(s, hold)
        s.Close()
    End Sub

Perhaps hold should be declared as an object?

i had that originaly it made no difference,


if i change the type pased to XmlSerializer to object it failes on the
x.Serialize(s, hold)

line with error:
An unhandled exception of type System.InvalidOperationException occurred in system.xml.dll

Additional information: There was an error generating the XML document.

insted of the line

Dim x As XmlSerializer = New XmlSerializer(GetType(settings))

with error:
An unhandled exception of type System.InvalidOperationException occurred in system.xml.dll

Additional information: There was an error reflecting MSN_No_Cut_Off.settings.

and the class settings has been declared with <Serializable()>
