Hi,
In my site which is in Dot Net Nuke to clear cache I want a button. Is there any code with the help of which I can do that.

Please haelp.

Where do you want to place this button? (There is a link in host settings that will do this)

Correct. It's at "Host Settings" / "Performance Settings" you'll see a link that says "Clear Cache".

Otherwise you'll need to modify the core code and that can be something that will hold you hostage for awhile. Not recommended.
