Exemples

L'exemple suivant crée un objet à sérialiser, une instance de la classe NetDataContractSerializer et une instance de la classe XmlDictionaryWriter. L'exemple utilise les méthodes WriteStartObject, WriteObjectContent et WriteEndObject pour écrire les données d'objet dans le document XML.

public sealed class ShowWriteStartObject
{

    public static void WriteObjectData(string path)
    {
        // Create the object to serialize.
        Person p = new Person("Lynn", "Tsoflias", 9876);

        // Create the writer.
        FileStream fs = new FileStream(path, FileMode.Create);
        XmlDictionaryWriter writer =
            XmlDictionaryWriter.CreateTextWriter(fs);

        NetDataContractSerializer ser =
            new NetDataContractSerializer();

        // Use the writer to start a document.
        writer.WriteStartDocument(true);

        // Use the serializer to write the start of the
        // object data. Use it again to write the object
        // data.
        ser.WriteStartObject(writer, p);
        ser.WriteObjectContent(writer, p);

        // Use the serializer to write the end of the
        // object data. Then use the writer to write the end
        // of the document.
        ser.WriteEndObject(writer);
        writer.WriteEndDocument();

        Console.WriteLine("Done");

        // Close and release the writer resources.
        writer.Flush();
        fs.Flush();
        fs.Close();
    }
