how to clear cookies

Hello friend

Deleting a cookie—physically removing it from the user's hard disk—is a variation on modifying it. You cannot directly remove a cookie because the cookie is on the user's computer. However, you can have the browser delete the cookie for you. The technique is to create a new cookie with the same name as the cookie to be deleted, but to set the cookie's expiration to a date earlier than today. When the browser checks the cookie's expiration, the browser will discard the now-outdated cookie. The following code example shows one way to delete all the cookies available to the application:

HttpCookie aCookie = default(HttpCookie);
int i = 0;
string cookieName = null;
int limit = Request.Cookies.Count - 1;
for (i = 0; i <= limit; i++) {
  cookieName = Request.Cookies(i).Name;
  aCookie = new HttpCookie(cookieName);
  aCookie.Expires = DateTime.Now.AddDays(-1);
  Response.Cookies.Add(aCookie);
}

public static void ClearCookies()
        {

            if (HttpContext.Current.Request.Cookies["Users"] != null)
            {
                HttpCookie aCookie = HttpContext.Current.Request.Cookies["Users"];
                aCookie.Expires = DateTime.Now.AddDays(-10);
                aCookie.Value = "";
                HttpContext.Current.Response.Cookies.Add(aCookie);
            }

        }

Hi,

Use this:

Response.Cookies.Clear();
//this will clear all the cookies created by the page.

Or

Response.Cookies["MyCookie"].Expires = DateTime.Now.AddDays(-5);
//this will clear a particular cookie created by the page.

All the best.

public static void RemoveCookie(string key)
        {
            //get cookies value
            HttpCookie cookie = null;
            if (HttpContext.Current.Request.Cookies[key] != null)
            {
                cookie = HttpContext.Current.Request.Cookies[key];
                
                //set its expiry date to earlier date
                cookie.Expires = DateTime.Now.AddDays(-1);
                HttpContext.Current.Response.Cookies.Add(cookie);
            }
