Answer
A destructor is a method called when an object is being cleaned up.
It is rarely used because memory is managed by the garbage collector.
Quick Answer
A destructor runs when the GC decides to clean up the object — you cannot call it yourself and cannot control when it runs. Avoid using destructors for resource cleanup; use IDisposable and using instead. Destructors delay garbage collection and add measurable overhead.
