Question

As some may be aware, I recently posted about high memory usage on my website and I have an idea that my thumbnailer may have something to do with this as I am not actively disposing of the instance when it has been used due to my misunderstanding how it works.

I am now looking at my code for the thumbnailer and would like some advice on when something would actually need disposing of, is it ONLY when you create a new instance of an object?

Like:

Target := System.Drawing.Bitmap.Create(Trunc(Width), Trunc(Height));
MyImage := Target.FromFile(PhotoPath);

So, my question would be, do I need to dispose of both Target and MyImage to make sure the GC does what it needs to do properly?

Thanks.

Check out this blog post on MSDN: .NET Memory Leak: To dispose or not to dispose, that’s the 1 GB question. The recommendation appears to be that you should be disposing.
