Hi, All,

Good day!

I would like to ask for help on how to solve below error:

Exception: The ObjectManager found an invalid number of fixups. This usually indicates a problem in the Formatter.

This is the piece of code where the error occurred:

 Private Function DeSerializeObject(ByVal PathFile As String) As Object
            Using FileStream As IO.Stream = New IO.FileStream(PathFile, IO.FileMode.Open, IO.FileAccess.Read, IO.FileShare.Read)
                Dim formatter As Runtime.Serialization.IFormatter = New Runtime.Serialization.Formatters.Binary.BinaryFormatter
                Me.Question = DirectCast(formatter.Deserialize(FileStream), UI.Tools.QuestionCollections)
                Return Me.Question
            End Using
        End Function

What should I do. I ran out of options. Thank you in advance for help.

google says that I need to create a custom SerializationBinder. Below is the code that I've added:

I just don't understand the string that should be replaced and what is the string replacement.

Class Binder
        Inherits SerializationBinder
        Public Overrides Function BindToType(assemblyName As String, typeName As String) As Type
            typeName = typeName.Replace("what_to_put_here?", "what_to_put_here?")
            Return Type.[GetType](typeName)
        End Function
        'method
    End Class
