Typically, types that use unmanaged resources implement the IDisposable or IAsyncDisposable interface to allow the unmanaged resources to be reclaimed. When you finish using an object that implements IDisposable , you call the object's Dispose or DisposeAsync implementation to explicitly perform cleanup.

You can do this in one of two ways:. The GC does not dispose your objects, as it has no knowledge of IDisposable. Dispose or IAsyncDisposable. The GC only knows whether an object is finalizable that is, it defines an Object. Finalize method , and when the object's finalizer needs to be called. For more information, see How finalization works.

For additional details on implementing Dispose and DisposeAsync , see:. Objects that implement System. This will enable the garbage collector to release the memory of the object directly when it is no longer in use. If we omit this call, the garbage collector will have to put the object on the finalizer que instead of releasing it. When the finalizer is suppressed, the GC is able to collect the object on the first run. The main work is done in the Dispose bool method.

It will first check a flag to ensure that we are not disposing twice. The disposing flag is important, because if called from dispose we want to release any managed resources early. If called from the finalizer it would be an error to touch any managed references. We have no idea if they are still alive, or if the GC freed those objects before freeing this object.

Any unmanaged resources should of course be released anyways. Sign Out Sign In Register. Latest Insider. Check out the latest Insider stories here. More from the IDG Network. How to resolve dependencies in ASP.
