MvcSerializer().Deserialize(serialized,SerializationMode....)

In asp.net mvc 3.0, I want to Deserialize and object which is stored in an input hidden filed.

Here is the Serializable class :

[Ser开发者_Python百科ializable]

public class RegistrationData
{
    public string Name { get; set; }
    public string Email { get; set; }
}

and the this is how i generate hidden field :

<%: Html.Serialize("regData", Model, Microsoft.Web.Mvc.SerializationMode.Signed)%>

but when I Deserialize it through following method, I get null values for my object :

var serialized = Request.Form["regData"];

        if (serialized != null)
        {
            regData = (RegistrationData)newMvcSerializer().Deserialize(serialized,SerializationMode.Signed); 

        }

Can any one help me please?
