Create a Cookie

You can add cookies to the Cookies collection in a number of ways. The following example shows two methods to write cookies:

Response.Cookies["UserName"].Value = "John";
Response.Cookies["UserName"].Expires = DateTime.Now.AddDays(1);

HttpCookie aCookie = new HttpCookie("LastVisit");
aCookie.Value = DateTime.Now.ToString();
aCookie.Expires = DateTime.Now.AddDays(1);
Response.Cookies.Add(aCookie);

 if(Request.Cookies["UserName"] != null)
 Label1.Text = Server.HtmlEncode(Request.Cookies["UserName"].Value);
