How to make a value type nullable with .NET XmlSerializer?

Question

Let\'s suppose I have this object:

[Serializable]

    public int Age { get; set; }
    public int MyClassB { get; set; }
}
[Serializab

Forget about Nullable ... ShouldSerializeXXX is a pretty solution. Here Age will be serialized upon your condition.

[Serializable]
public class MyClass
{
    public int Age { get; set; }
    public int MyClassB { get; set; }

    #region Conditional Serialization
    public bool ShouldSerializeAge() { return age > 0; }
    #endregion
}

[Serializable]
public class MyClassB
{
    public int RandomNumber { get; set; }
}
