You develop a serializable class for persisting objects as files.
Every time an object is serialized, you have to update the database with the name of the object and location of that file.
You elect to employ the OnSerialized attribute to achieve this objective.
You now need to apply the OnSerialized attribute to a certain method.
What should you do?（）

You have recently created a serializable class named Vehicle.
The class is shown below:
[Serializable]
public class Vehicle{
public string VIN;
public string Make;
public string Model;
public string Year;
}
You are planning to create a custom formatter class to control the formatting of Vehicle objects when they are serialized.
You need to ensure that is achieved with as little development effort as possible.
