I would suggest , to use .Net's IDisposable interface if your are thinking of to release instance after its usage.
See a sample implementation below.
public class Car : IDisposable
{
public void Dispose()
{
Dispose(true);
// any other managed resource cleanups you can do here
Gc.SuppressFinalize(this);
}
~Car() // finalizer
{
Dispose(false);
}
protected virtual void Dispose(bool disposing)
{
if (!_disposed)
{
if (disposing)
{
if (_stream != null) _stream.Dispose(); // say you have to dispose a stream
}
_stream = null;
_disposed = true;
}
}
}
Now in your code:
void main()
{
using(var car = new Car())
{
// do something with car
} // here dispose will automtically get called.
}
