SerializationException

There is a problem with the instance being written.

The following example creates an object to serialize, an instance of the DataContractSerializer, and an instance of the XmlDictionaryWriter class. The example uses the WriteStartObject, WriteObjectContent, and WriteObjectContent methods to write the object data into the XML document.

Public Shared Sub WriteObjectContentInDocument(ByVal path As String) 
    ' Create the object to serialize. 
    Dim p As New Person("Lynn", "Tsoflias", 9876)

    ' Create the writer. 
    Dim fs As New FileStream(path, FileMode.Create)
    Dim writer As XmlDictionaryWriter = XmlDictionaryWriter.CreateTextWriter(fs)

    Dim ser As New DataContractSerializer(GetType(Person))

    ' Use the writer to start a document.
    writer.WriteStartDocument(True)
    ' Use the writer to write the root element.
    writer.WriteStartElement("Company")
    ' Use the writer to write an element.
    writer.WriteElementString("Name", "Microsoft")

    ' Use the serializer to write the start, 
    ' content, and end data.
    ser.WriteStartObject(writer, p)
    ser.WriteObjectContent(writer, p)
    ser.WriteEndObject(writer)

    ' Use the writer to write the end element and 
    ' the end of the document.
    writer.WriteEndElement()
    writer.WriteEndDocument()

    ' Close and release the writer resources.
    writer.Flush()
    fs.Flush()
    fs.Close()

End Sub
