使用Razor在Asp.net MVC中显示重新登录（即注销后再次登录）上的最后一个cookie值

Question

I am working on Asp.net MVC with Razor view engine with C#. I have a login form and on login I create a Cookie for userid, and on logout I remove this cookie evrything works fine yet. but the problem starts when I Login again it still shows the value of Previous Login's userid.

The code of creating cookie is

HttpCookie newCookie = new HttpCookie(cookieId, cookieValue);
newCookie.Expires = DateTime.Today.AddDays(30);
HttpContext.Current.Response.Cookies.Add(newCookie);

And to remove cookie

if (HttpContext.Current.Request.Cookies[cookieId] != null)
{
    HttpContext.Current.Response.Cookies[cookieId].Value = null;
}

I have remove the cookie on login if there exist but still it is not working , please help me......

Answer 1

You can remove your cookie like below,

if ( Request.Cookies["MyCookie"] != null )
{
    var c = new HttpCookie( "MyCookie" );
    c.Expires = DateTime.Now.AddDays( -1 );
    Response.Cookies.Add( c );
}
