c# program takes up lots of memory

Question

Possible Duplicate:
Best .NET memory and performance profiler?

My C# program, a web scraper, makes extensive use of async HttpWebRequests, Regex, and HTML agility pack. It's multi threaded using the ThreadPool.QueueUserWorkItem method.

It starts off using around 600,000 K of memory and eventually climbs to over 1,000,000 K.

How can I track what's taking up the most memory and clean it up so it's less resource intensive?

Thanks

@Adam, you are off by a factor of 1000, though the usage of KB instead of MB is pretty non-standard. — Kirk Woll, May 31 '12 at 02:26

Use a memory profiler - they can help to analyse such problems, for example:

http://memprofiler.com/ (commercial, managed PLUS unmanaged integrated in one profiler!)
http://www.red-gate.com/products/dotnet-development/ants-memory-profiler/ (commercial)
CLR Profiler from MS (free)

Your best bet is to use a profiler. I've had great success with using the Redgate ANTS Performance Profiler, which is not free. There may be other good choices out there.
