c# - How to delete Cookies from windows.form?

Question

I am working with the Webbrowser control on a windows.form application written in C#. I would like to write a method for deleting the cookies from the Webbrowers control after it visits a certain site. Unfortunately, I don't know how to do that exactly and haven't found a lot of help on the internet.

If anyone has experience actually doing this, not just hypothetical because it might be trickier than it seems, I don't know.

int count = webBrowser2.Document.Cookie.Length;
webBrowser2.Document.Cookie.Remove(0,count);

I would just assume something like the above code would work but I guess it won't. Can anyone shed some light on this whole cookie thing?

Answer 1

If you have JavaScript enabled you can just use this code snippet to clear to clear the cookies for the site the webbrowser is currently on.

webBrowser.Navigate("javascript:void((function(){var a,b,c,e,f;f=0;a=document.cookie.split('; ');for(e=0;e<a.length&&a[e];e++){f++;for(b='.'+location.host;b;b=b.replace(/^(?:%5C.|[^%5C.]+)/,'')){for(c=location.pathname;c;c=c.replace(/.$/,'')){document.cookie=(a[e]+'; domain='+b+'; path='+c+'; expires='+new Date((new Date()).getTime()-1e11).toGMTString());}}}})())")

It's derived from this bookmarklet for clearing cookies.
