推荐答案

规则是-不要使用静态类.

您需要使用实例，并将信息存储在cookie或Session中而不是类中.

静态的整个想法是每个应用程序只有一个-在ASP.NET中，这不是您可以使用的解决方案，因为两个用户可能无法共享一个应用程序，并且该应用程序很可能在一个用户被终止之前重新启动完成了.

在ASP中，应用程序在第一个用户开始使用它时启动，但是它可以(并且通常会在页面加载结束时结束)并在用户回发时重新加载.您不能将信息存储在静态类中，甚至不能期望同一用户可以使用它！

The rule is - don''t use static classes.

You need to use instances, and to store information either in cookies or in the Session instead of classes.

The whole idea of Static is that there is only one per application - in ASP.NET that is not a solution you can use, as two users may opr may not share an application, and the application may well be terminated and restarted before one user has finished with it.

In ASP, the application starts when the first user starts to use it, but it can (and often will) be ended at the end of that page load and be reloaded when the user does a post back. You can''t store information in a static class and expect it to even be available to the same user!
