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

  • IDisposable is implemented explicitly and provides the Dispose() method, which is called manually or via the using construct. This allows timely release of managed and unmanaged resources.

  • The finalizer is a method called by the garbage collector before the object is destroyed, if Dispose() was not called. It acts as a backup mechanism to release unmanaged resources, but its invocation time is indefinite.

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