Answer 1

You really need to use a code Profiler. These will tell you exactly what's happening, where the memory is being used up, etc.

FYI: It's rarely where you think it is.

Answer 2

long bytes = System.Diagnostics.Process.GetCurrentProcess().WorkingSet64;

Answer 3

You can try GC.GetTotalMemory:

Retrieves the number of bytes currently thought to be allocated. A parameter indicates whether this method can wait a short interval before returning, to allow the system to collect garbage and finalize objects.

The important thing to note is this part: "Retrieves the number of bytes currently thought to be allocated". This means that this method may not be 100% accurate - as long as you know this going in, you should be able to get a rough idea of your virtual memory utilization at a given point in your application execution.

Edit: Let me now offer a different solution that will probably be more productive: use perfmon and the CLR performance counters.
