在登录后获得Membership.GetAllUsers()的例外:"项目已被添加"

Question

我有两个共享会员提供商的网站.其中一个是ASP Playground站点,另一个是安装了ASP Playground站点集成包的站点.我们称他们为ASPPG网站和SIP网站.

我在SIP站点上运行Membership.GetAllUsers()时有时会出错.SIP拒绝此方法,因此它不是标准的ASP.NET版本.

它有时只会发生.我注意到只有在其中一个成员发生某种变化时才会发生这种情况.然后它必须重新创建在调用Membership.GetAllUsers()时存储所有用户的哈希表,这就像这种娱乐在某种程度上出错了.

除了我粘贴在"administratoren"下面的例外,登录的用户名已经改变了一些信息.

通过更新web.config强制网站卸载没有帮助.它无助于重新启动IIS或完全重新启动服务器.异常出现后,每次调用Membership.GetAllUsers()时都会一直显示.突然之间,异常消失,并且再次可以登录并运行Membership.GetAllUsers(),没有任何异常.它几乎看起来像错误在数据库中,并且修复错误的方法是加载ASPPG站点的任何页面.然后错误在SIP站点上得到修复.

导致异常的原因是什么？如何阻止它？

完整的例外是这样的:

提前致谢 :)

编辑:添加了MemberInfo.cs的新来源并更新了我收到的错误消息.请注意,堆栈跟踪仍然是旧的,因此它所指的行号可能有点偏差.

编辑:有关错误的大量信息已更改.添加了新的MemberInfo.cs.从登录方法中删除了代码,因为我现在知道这不是错误的原因.

事实证明，该站点将一些会话数据存储在表中。
在某些情况下，该表会过时，然后网站就会崩溃。
我添加了一些清理代码，以便在发生错误时清理表。

感谢所有试图帮助我的人:)
