創(chuàng)建Cookies

  public void UserCookies()
  {
   if(Request.Browser.Cookies == true)
   {
    if(Request.Cookies["UserLogin"]==null)
    {
     HttpCookie UserCookie=new HttpCookie("UserLogin",DateTime.Now.ToString());
     UserCookie.Value=Txt_Uname.Text;
     UserCookie.Expires = DateTime.Now.AddDays(1);
     Response.Cookies.Add(UserCookie);
     Request.Cookies.Set(UserCookie);
    
    }

   }
  }

退出

   if(HttpContext.Current.Request.Cookies["UserLogin"]!=null)
   {
    HttpCookie UserCookie= Request.Cookies["UserLogin"];
    UserCookie.Expires=DateTime.Now.AddDays(-1);
    HttpContext.Current.Response.Cookies.Add(UserCookie);
   }

判斷Cookies是否為空

if(Request.Cookies["adminlogin"]==null)

{

  ....

}
