sérialisation partielle DataContract

Question

J'ai un DataContract qui ressemble à:

[DataContract(Name = User.Root, Namespace = "")] 
    public class RegisterUser 
    { 
    [DataMember(Name = User.EmailAddress)] 
    public string EmailAddress { get; set; } 
    [DataMember(Name = User.UserName)] 
    public string UserName { get; set; } 
    [DataMember(Name = User.Password)] 
    public string Password { get; set; } 
    [DataMember(Name = User.FirstName)] 
    public string FirstName { get; set; } 
    [DataMember(Name = User.LastName)] 
    public string LastName { get; set; } 
    [DataMember(Name = User.PhoneNumber)] 
    public string PhoneNumber { get; set; } 
    [DataMember(Name = "RequestMessage")] 
    public string RequestMsg { get; set; } 
    } 

Et je voudrais obtenir les éléments hors de lui. Donc, au lieu de <ROOT> <Element1/>...</ROOT>. Je voudrais juste obtenir <Element1/> (pour la validation partielle xsd).

Je pensais que je pouvais utiliser cette fonction:

public static string Serialize<T>(T obj) 
{ 
    DataContractSerializer ser = new DataContractSerializer(obj.GetType()); 
    String text; 
    using (MemoryStream memoryStream = new MemoryStream()) 
    { 
    ser.WriteObject(memoryStream, obj); 
    byte[] data = new byte[memoryStream.Length]; 
    Array.Copy(memoryStream.GetBuffer(), data, data.Length); 
    text = Encoding.UTF8.GetString(data); 
    } 
    return text; 
} 

et passer juste

string str = Serialize(test.EmailAddress); 

Cela fonctionne très bien, mais le xml ressemble:

"<string xmlns=\"http://schemas.microsoft.com/2003/10/Serialization/\">myemail.com</string>" 

J'ai perdu le DataMember Info. Comment puis-je conserver cela aussi?

Utilisation WriteObjectContent au lieu de WriteObject: http://msdn.microsoft.com/en-us/library/ms573853.aspx
