cookie与session用法

//记住的用户名
                HttpCookie GetCookieUsersName = Request.Cookies["Login_UsersName"];
                if (GetCookieUsersName != null && !string.IsNullOrEmpty(GetCookieUsersName.Value))
                {
                    userName.Value = GetCookieUsersName.Value;
                }


//记住用户名
                                HttpCookie CookieUsersName = new HttpCookie("Login_UsersName", userName.Value.Trim());
                                Response.Cookies.Add(CookieUsersName);
//十天免登录
                                //Std.Page.StdUserControl.setSaveTime = 10;

简单SESSION用法
{

session中存放一些值，比如
Session["UserName"]="admin"
Session["Pass"]="admin"

然后在另外一个页面中，你可以使用它：
If(Session["UserName"]="admin")
..........

}
#region 记录登录的Session
                            SessionUser sessionUser = new SessionUser();
                            sessionUser.UserId = user.UserId;
                            sessionUser.Account = user.Account;
                            sessionUser.UserName = user.RealName;
                            sessionUser.Gender = user.Gender;
                            sessionUser.Password = user.Password;
                            sessionUser.Code = user.Code;
                            sessionUser.Secretkey = user.Secretkey;
                            sessionUser.DepartmentId = user.DepartmentId;
                            sessionUser.LoginDate = DateTime.Now.ToString();
                            RequestSession.AddSessionUser(sessionUser);
                            #endregion

//取出session
SessionUser sessionUser = new SessionUser();
            sessionUser = RequestSession.GetSessionUser();

Session.Abandon();//清除全部Session
//清除某个Session
Session["UserName"] = null;
Session.Remove("UserName");

vb.net版本

'''清除全部

Session.Abandon()

Session.Clear()

'''清除某个Session

Session("UserInfo") = Nothing

Session.Remove("UserInfo")
