Finalizer is not called

Question

I have a class in C # where I want to close some communication ports properly when my class is deleted. However, the finalizer is never called when I exit the program. Why is this? Am I doing something wrong?

I call the utility manually, which goes through and closes all messages. This does not work.

Here is the finalizer I'm using:

~Power()
{
    Dispose(false);
}

Answer 1

The finalizer (which you use here) is called only during the completion phase, which will be executed during the GC.

If you implement IDisposable correctly, this should never be called. I will talk about this in detail in my series on IDisposable .
