Problems clearing cookies on exit

jy270627

I saved cookies in the landing page
Response.Cookies ["TrueName"]. Value = sdr ["TrueName"]. ToString ();
Response.Cookies ["TrueName"]. Expires = DateTime.Now.AddMinutes (30);

Expires in 30 minutes

In the Page_Load event of the exit page
Response.Cookies.Clear ();
In this way, I can still read the cookie value on other pages, what's going on?

Later I wrote it like this
Response.Cookies ["TrueName"]. Value = "";
Response.Cookies.Clear ();

The result is still the same. The value of Cookies can still be read on other pages. Why can't it be cleared?

Response.Cookies ["TrueName"]. Value = "";
Response.Cookies ["TrueName"]. Expires = try -1 seconds;

Expires problem.

jy270627

Response.Cookies ["TrueName"]. Value = "";
Response.Cookies ["TrueName"]. Expires = DateTime.Now.AddMinutes (-1);
Response.Cookies.Clear ();

This still doesn't work ~!

Response.Cookies ["TrueName"]. Expires = DateTime.Now;

Or not

After reading the COOKIES page, it is a new window. Does the main window quit and the new window will not work?

Add cookies:

HttpCookie cookie = new HttpCookie ("MyCookie");

cookie1.Values.Add ("TrueName", sdr ["TrueName"]. ToString ());

Response.Cookies.Add (cookie);

========================================

When logging out:
HttpCookie cookie = Request.Cookies ["MyCookie"];
cookie.Expires = DateTime.Now.AddDays (-1);
Response.Cookies.Add (cookie);

/// <summary>
/// delete cookie, pass value cookiename
/// </ summary>
/// <param name = "cookiename"> </ param>
public void delcookie (string cookiename)
{
HttpCookie cookie = new HttpCookie ("" + cookiename + "", null);
cookie.Expires = DateTime.Now.AddDays (-1);
System.Web.HttpContext.Current.Response.Cookies.Add (cookie);
System.Web.HttpContext.Current.Response.Cookies.Remove ("cookie");
}
