How do I force the Dispose method to be called automatically, as clients can forget to call the Dispose method?

Question

How we can force a function to be called only once. I can do this using some static variable or using boost library, but is there some other way to do this as I don't want to use any of the earlier way. Function is a non member function of any class.

Answer 1

Call the Dispose method in the Finalize method and in the Dispose method to suppress the Finalize method from using "GC.SuppressFinalize". The following is the sample code of the pattern. This is the best way to clean our unallocated resources, and yes do not forget, we do not get the hit of running the Garbage Collector twice.

public class CleanClass : IDisposable
    {
        public void Dispose()
        {
            GC.SuppressFinalize(this);
        }
        protected override void Finalize()
        {
            Dispose();
        }
    }
