序列化部分DataContract

Question

我有一個DataContract，看起來像：

[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; } 
    } 

，我想擺脫它的元素。因此，而不是 <ROOT> <Element1/>...</ROOT>。我只想得到<Element1/>（用於部分xsd驗證）。

我想我可以使用此功能：

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; 
} 

，只是把它傳遞

string str = Serialize(test.EmailAddress); 

這偉大工程，但XML的樣子：

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

我失去了數據成員信息。我怎樣才能保留這一點？

使用WriteObjectContent代替WriteObject： http://msdn.microsoft.com/en-us/library/ms573853.aspx
