Why call dispose(false) in the destructor?

Question

What follows is a typical dispose pattern example:

 public bool IsDisposed { get; private set; }

  #region IDisposable Members

  public void Dispose()
  {
         


        

Answer 1

There are no destructors in C#. That's a Finalizer, which is a different thing.

The distinction is whether you need to clean up managed objects or not. You don't want to try to clean them up in the finalizer, as they may themselves have been finalized.

I just recently happened to look at the Destructors page of the C# Programming Guide. It shows that I was mistaken in my answer, above. In particular, there is a difference between destructor and finalizer:

class Car
{
    ~Car()  // destructor
    {
        // cleanup statements...
    }
}

is equivalent to

protected override void Finalize()
{
    try
    {
        // Cleanup statements...
    }
    finally
    {
        base.Finalize();
    }
}
