Cookies in login page

Write this code to create cookies and store username within a cookies

  HttpCookie obj=new HttpCookie("MyCookieName");
  obj.Value=TextBox1.Text;
  Response.Cookies.Add(obj);

write this code to read cookies

string CookieValue;
// We need to perform this check first, to avoid null exception
// if cookie not exists
if(Request.Cookies["MyCookieName"] != null)
  CookieValue = Request.Cookies["MyCookieName"].Value;
 

To set expiry date of cookies write this code bellow the line of create cookies.


obj.Expires = DateTime.Now.AddDays(1);


To delete existing cookie we actually just set its expiration time to some time in the past. You can do it with code like this:
obj.Expires== DateTime.Now.AddDays(-1);
