Answer
Destructors execute when the garbage collector decides to free an object.
They cannot be called manually and should be used only as a final safety mechanism.
Quick Answer
A destructor runs when the GC decides to finalize an object — you cannot predict when. It cannot be called manually and runs on a dedicated finalizer thread. Use it only as a last resort safety net. Prefer Dispose() and the using statement for deterministic resource cleanup.
