How does the IDisposable interface differ from the finalizer in managed C# code?

In C#, the IDisposable interface and the finalizer (finalizer) serve to release resources but work differently:

• IDisposable is implemented explicitly and provides a Dispose() method, which is called manually or through a using statement. This allows for timely release of managed and unmanaged resources.

• Finalizer is a method called by the garbage collector before the object is destroyed if Dispose() was not called. It acts as a fallback mechanism for releasing unmanaged resources, but its timing is indefinite.

Thus, IDisposable ensures deterministic resource release, while the finalizer is nondeterministic and more costly in terms of performance.
