登陆Cookies使用方法

下面代码放在验证登陆之后，保存客户登陆信息

                HttpCookie LoginCookie=new HttpCookie("qwersdfawer");
                LoginCookie["qwerzsdvfvwerfq"]=Common.ToBase64(TxtUsername.Text);
                LoginCookie["vcxzvasdfqwer"]=Common.ToBase64(TxtCompID.Text);
                LoginCookie["sadfqwerqwvxcv"]=Common.ToBase64(TxtPass.Text);
                switch(RdlCookie.SelectedIndex)
                {
                    case 0:
                        LoginCookie.Expires=DateTime.Now.AddYears(1);
                        break;
                    case 1:
                        LoginCookie.Expires=DateTime.Now.AddMonths(1);
                        break;
                    case 2:
                        LoginCookie.Expires=DateTime.Now.AddDays(1);
                        break;
                    case 3:
                        LoginCookie.Expires=DateTime.Now;
                        break;
                }
                Response.Cookies.Add(LoginCookie);

下面代码放在Global.asax

            HttpCookie LoginCookie=Request.Cookies["qwersdfawer"];
            if(LoginCookie!=null&&LoginCookie["vcxzvasdfqwer"]!=null&&LoginCookie["qwerzsdvfvwerfq"]!=null&&LoginCookie["sadfqwerqwvxcv"]!=null)
            {
                string dir=Common.FromBase64(LoginCookie["vcxzvasdfqwer"]).ToString();
                string username=Common.FromBase64(LoginCookie["qwerzsdvfvwerfq"]);
                string password=Common.FromBase64(LoginCookie["sadfqwerqwvxcv"]);
                ses user=new ses(dir,username,password);
                if(ses.checkuser(user))
                {
                    Session["user"]=user;
                    Session["username"]=username;
                    Session["Compid"]=dir;
                }
            }

登出

            Session["username"]="";
            Session["Compid"]="";
            Session["menu"]="";
            Session["user"]=null;
            Response.Cookies.Remove("qwersdfawer");
            Response.Cookies.Clear();
            this.Dispose();
            Response.Redirect("index.aspx");
