Try this:

ASP.NET

<%@ Page Language="C#" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">

    void Page_Load()
    {
        ArrayList colCookies = new ArrayList();
        for (int i = 0; i < Request.Cookies.Count; i++)
            colCookies.Add(Request.Cookies[i]);

        grdCookies.DataSource = colCookies;
        grdCookies.DataBind();
    }
</script>
<html xmlns="http://www.w3.org/1999/xhtml" >
<head id="Head1" runat="server">
    <title>Get All Cookies</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
    
    <asp:GridView
        id="grdCookies"
        Runat="server"/>
        
    </div>
    </form>
</body>
</html>

Well.. HttpRequest.Cookies is a collection. So use LINQ:

C#

var qry = from cookieName in Request.Cookies.Keys
          where cookieName.StartsWith("google")
          select cookieName;

foreach(var item in qry)
{
   // get the cookie and deal with it.
   var cookie = Request.Cookies[item];
}

Bottom line: you can't get away from iterating over the entire cookie collection. But you can do it easily using LINQ.

Or

C#

void Page_Load()
    {

        ArrayList colCookies = new ArrayList();
        for (int i = 0; i < Request.Cookies.Count; i++)
            colCookies.Add(Request.Cookies[i]);

        grdCookies.DataSource = colCookies;
        grdCookies.DataBind();
    }

View this[^] link for more information.

Removing cookie from your entire application try this:

C#

string[] cookies = Request.Cookies.AllKeys;
foreach (string cookie in cookies)
{
            Response.Cookies[cookie].Expires = DateTime.Now.AddDays(-1);
}

It should get all the cookies that are currently set whether it's the page or not. You may want to check to see what the Path is set for the cookies. It could be that you have created cookies that are restricted to a page or directory. Setting the path to / when creating a cookie should allow all cookies for that domain name to be visible.
