Copy codeThe Code is as follows:
Response. Cookies ["Cookie name"]. Value = "";

Read Cookie Syntax:
Copy codeThe Code is as follows:
If (Request. Cookies ["Cookie name"]! = Null)

System. Web. HttpContext. Current. Response. Cookies ["Cookie name"]. Value = "";

Read Cookie Syntax:
Copy codeThe Code is as follows:
If (System. Web. HttpContext. Current. Request. Cookies ["Cookie name"]! = Null)

String cookieValue = HttpContext. Current. Request. Cookies ["Cookie name"]. Value. ToString ();
}
