Can I / Should I serialize a constant variable in a C# class?

I am implementing the ISerializable interface for my class.

I have a constant variable in the class like:

public const decimal Cost = 3.2M

When I implement the GetObjectData method, can I / should I serial this variable?

When I implement the GetObjectData method, can I / should I serial this variable?

Absolutely not.

Even if you did write it out, it's not like you could change the value of the constant when you read it back in again.

More generally, you shouldn't serialize static fields at all (and const implies static). Anything static is not part of the state of an instance, and it's the data within the instance that you're trying to serialize.
