How do you free system ram when creating and disposing user controls

Question

I have a c# application that is composed of various screens which is each a respective user control. The application requires a lot of switching between the various screens and is also graphic intensive. Each control is disposed once the next control is invoked and the garbage collector is called to release the system resources. The thing is for some reason the system memory is never released and at some point after multiple screen changes it inevitably crashes. Any Ideas would be greatly appreciated.

Answer 1

If I had to guess, you're registering lots of events with these controls but not de-registering before they get "disposed", so they're not getting collected by the GC.

This is a hugely complex subject. I'd strongly suggest investing in a decent memory profilter (a hundie or two) to help you narrow down where your application is crashing.
