问如何用可序列化对象数组反序列化类

EN

[ProtoContract]
class MyClass
{
    .
    .

    public MyClass()
    {
    }

    object[] elements;

    [ProtoMember(1)]
    string[] SerilizedElements;

    [ProtoMember(2)]
    string[] TypeOfElements;

    [ProtoBeforeSerialization]
    void initBeforeSerilize()
    {
        TypeOfElements = new string[elements.Length];

        SerilizedElements = new string[elements.Length];

        for (int i = 0; i < elements.Length; i++)
        {
                TypeOfElements[i] = elements[i].GetType().ToString();

                using (MemoryStream ms = new MemoryStream())
                {
                    Serializer.Serialize(ms, elements[i]);
                    SerilizedElements[i] = Encoding.UTF8.GetString(ms.ToArray());
                }
        } 
    }

    [ProtoAfterDeserialization]
    void initAfterSerilize()
    {
        for (int i = 0; i < SerilizedElements.Length; i++)
        {
              Type t = Type.GetType(TypeOfElements[i]);

              using(MemoryStream ms=new MemoryStream(Encoding.ASCII.GetBytes(SerilizedElements[i])))
              {
                    //I don't know how to write this line
                    elements[i]=Serializer.Deserialize<t>(ms);
              }
        }
    }
}
