About Dispose method

[Lost User]

I don't quite understand what dispose method exacly does. From manual I read that it "frees up ny ressources being used". But what happens to the object after calling dispose method ? Is it destroyer ? Also - is there any link between an object's destructor and dispose method ? Regards, Desmond

Lately, Heath[^] provided me a very cool link about this subject: http://www.albahari.com/value%20vs%20reference%20types.html[^] I hope it helps!

IDisposable.Dispose (you must implement IDisposable for this to be used correctly) is best used to free native resources (since many classes in .NET use native HANDLEs). You can also use it to dispose child objects and set references to null. This is not a destructor, though. In fact, many times when the Dispose method cleans-up the resources, it will tell the GC to not call the destructor since there's nothing left to do (be sure you clean-up all resources before doing so, though):

public void Dispose()
{
// Clean up native resources and any managed resource you might have.
GC.SuppressFinalize(this);
}

For a more thorough example, see the documentation for the GC.SuppressFinalize method in the .NET Framework SDK.
