I have a web app (VS 2005 / .Net v 2.050727) that uses a session variable to store a dataset. I''m using a grid that has link buttons in some of the columns. When I click on a link it opens another browser window that accesses the session variable. Sometimes the session variable has a value and sometimes it will return null. Any ideas?????????

推荐答案

取决于系统的配置，有几个原因可以回收应用程序的工作进程因此消除了所有存储的会话变量.请查看我对这个问题的解决方案:对象参考未设置为对象实例 [ ^ ].还请查看此解决方案的注释.这应该给您一些想法.

希望这会有所帮助！

Depending on the configuration of your system there are several reasons for the application''s worker process to be recycled thus eliminating all stored session variables. Please see my solution to this question: object reference not set to instance of object[^]. Also look into the comments of this solution. This should give you some ideas.

Hope this helps!
