Public class is not public

[VladC#]

I'm trying to serialize some public class, but it doesn't compleate correctly, I receive an error message that class is not public. there is an all code of my console application (from MSDN):

Imports System.IO
Imports System.Xml.Serialization

Module Module1

Sub Main()
SerializeObject("person.xml")
End Sub

Private Sub SerializeObject(ByVal filename As String)
Dim serializer As New XmlSerializer(GetType(OrderedItem))
' Create an instance of the class to be serialized.
Dim i As New OrderedItem()
' Set the public property values.
With i
.ItemName = "Widget"
.Description = "Regular Widget"
.Quantity = 10
.UnitPrice = CDec(2.3)
End With
' Writing the document requires a TextWriter.
Dim writer As New StreamWriter(filename)
' Serialize the object, and close the TextWriter.
serializer.Serialize(writer, i)
writer.Close()
End Sub

' This is the class that will be serialized.
Public Class OrderedItem
Public ItemName As String
Public Description As String
Public UnitPrice As Decimal
Public Quantity As Integer
End Class

End Module

how can i resolve this issue?

1) The class cannot be inside a module (I believe)
2) The class hasn't been marked with the Serializable attribute.
3) I'm not 100% sure about this, but I don't know if fields can be serialized, I think (and it's a big think) you have to implement them as actual properties.

I can't think of any valid reason to ever declare a class inside a module.

1. thank you, you really helped me
2. if you use XML serialization you should not mark class with Serializable attribut.
3. fields can be serialized but it is optionally
