不定义类型的XML序列化

Question

Is there any way to build a generic method for XML serialization and deserialization that doesn't require a bunch of gymnastics including pre-defining types using something like XmlInclude? The code that I need to build cannot rely on pre-defined types. I'm assuming Reflection could be used here, but I can't find an adequate solution. The ones I've tried from NuGet each have limitations:

• Polenter seems to produce unusable output that cannot be deserialized
• Global, Netfx requires type definitions ahead of time
• Bender is beautiful but doesn't seem to support objects embedded within the object being serialized
• XSerializer and JsonFX are what I need on the serialization side but the output won't deserialize

The standard XmlSerializer won't work for obvious reasons (pre-defined types, XmlInclude, etc).

A simple example of what I need to serialize and then deserialize:

    public class c1
    {
        public string name { get; set; }
        public object obj { get; set; }
    }

    public class c2
    {
        public string city { get; set; }
    }

    public static void Main(string[] args)
    {
        c1 class_1 = new c1();
        c2 class_2 = new c2();
        class_1.name = "david";
        class_2.city = "chicago";
        class_1.obj = class_2;

        string xml = <insert here>;
        Console.WriteLine("XML: " + xml);

        c1 deserialized = new c1();
        deserialized = <insert here>;
        Console.WriteLine("City: " + ((c2)c1.obj).city);
    }

Does something like this even exist?

I'm not sure what you mean by "not defining types". If it's an object your code is working with, it has a type. The easiest thing to do would be to write your code to work against ISerializable - then it can work with any serializable type - even those that your code isn't aware of at build time. Alternatively, if you are working with dynamic objects (object's whose members are defined at runtime) check out this question for an example of making an ISerializable DynamicObject: https://stackoverflow.com/a/7501960/518955
