How can I remove all my site's cookies from the client, either in ASP.NET/C# or JavaScript? Basically I would like to click a button or link on the page and have it clear all the cookies for the site. I don't need to know the name of every cookie, do I?

Reset to default 4 
foreach (string key in Request.Cookies.AllKeys)
{
    HttpCookie cookie = new HttpCookie(key);
    cookie.Expires = DateTime.UtcNow.AddDays(-7);
    Response.Cookies.Add(cookie);
}

As I wrote before to @mwilson, you cannot directly delete a cookie on a user's puter. However, you can direct the user's browser to delete the cookie by setting the cookie's expiration date to a past date.

To delete all cookies just browse the Response.Cookies collection with a foreach loop and replace the date of each cookie with a past date.
