How to free virtual memory ?

[mehdiab]

I have a crawler application (with C#) that downloads pages from web . The application take more virtual memory , even i dispose every object and even use

GC.Collect()

.

This , have 10 thread and each thread has a socket that downloads pages . In each thread , i have a

byte[] buffer

that store content of page , and have an

string str_content

that i store in it , content of page in string . I have a Sytem.Timer that every 3 second chech , if each thread has been stopped , assign it new thread and start it.

I use dispose method and even use

GC.Collect()

in my application , but in 3 hour my application take 500 MB on virtual memory (500 MB on private bytes in Process explorer) . Then my system will be hang and i should restart my pc .

would it be rude , If i assign my byte[] and string to null ?

Is there any way that i use to free virtual memory ?

Thanks .

GC.Collect()
won't do you any good if you don't dispose of objects you are making. All GC.Collect does is cause garbage collection to take place 'now' instead of when the OS feels like it.

If you memory use keeps climbing then you have a problem with not disposing of objects. That's where you need to concentrate your efforts.
