xml and serilisation

[Guest 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

[divil]

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()>
