推荐答案

的一种方法是，
在会话的情况下到期，每一个动作，你必须检查它的会话，如果它为null，则重定向到登录页面。

One way is that In case of Session Expire, in every action you have to check its session and if it is null then redirect to Login page.

但是，这是非常忙碌的方法
要通过这个来，你需要创建自己的 ActionFilterAttribute 这将做到这一点，你只需要在每一个动作方法中添加这个属性。

But this is very hectic method To over come this you need to create your own ActionFilterAttribute which will do this, you just need to add this attribute in every action method.

下面是它覆盖ActionFilterAttribute类。<​​/ P>

Here is the Class which overrides ActionFilterAttribute.

public class SessionExpireFilterAttribute : ActionFilterAttribute
    {
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            HttpContext ctx = HttpContext.Current;

            // check if session is supported
            CurrentCustomer objCurrentCustomer = new CurrentCustomer();
            objCurrentCustomer = ((CurrentCustomer)SessionStore.GetSessionValue(SessionStore.Customer));
            if (objCurrentCustomer == null)
            {
                // check if a new session id was generated
                filterContext.Result = new RedirectResult("~/Users/Login");
                return;
            }

            base.OnActionExecuting(filterContext);
        }
    }

然后在行动只是添加此属性，像这样：

Then in action just add this attribute like so:

[SessionExpire]
public ActionResult Index()
{
     return Index();
}

这会做你的工作。
