c# - How to unit test if my object is really serializable?

Question

I am using C# 2.0 with Nunit Test. I have some object that needs to be serialized. These objects are quite complex (inheritance at different levels and contains a lot of objects, events and delegates).

How can I create a Unit Test to be sure that my object is safely serializable?

Here is a generic way:

public static Stream Serialize(object source)
{
    IFormatter formatter = new BinaryFormatter();
    Stream stream = new MemoryStream();
    formatter.Serialize(stream, source);
    return stream;
}

public static T Deserialize<T>(Stream stream)
{
    IFormatter formatter = new BinaryFormatter();
    stream.Position = 0;
    return (T)formatter.Deserialize(stream);
}

public static T Clone<T>(object source)
{
    return Deserialize<T>(Serialize(source));
}
