What are finalizers in C# and how do they work?

Finalizers in C# are special methods that are called when an object is being garbage collected. They allow you to clean up unmanaged resources.

Can you give me an example of a finalizer in a C# class?

Sure! Here's a simple example:

class MyClass {
    ~MyClass() {
        // Cleanup code here
    }
}

When should I use a finalizer?

You should use a finalizer when your class holds unmanaged resources that need to be released, like file handles or database connections.

Are there any performance implications of using finalizers?

Yes, finalizers can impact performance because they add overhead to garbage collection. It's often better to implement IDisposable instead.
