Why does the traditional Dispose pattern suppress finalize?

Question

Assuming this as the traditional Dispose pattern (taken from devx but seen on many websites)

class Test : IDisposable
{
  private bool isDisposed = false;

          


        

Answer 1

As noted on MSDN executing the Finalize method is costly. By calling dispose you've already self finalized your class so the finalizer doesn't need to be called. The finalizer is implemented in case the Dispose is never called directly by your code (or whoever 'owns' the instance).
