Question

我知道这个错误是什么，如何修复它等等。

我的问题是，我不知道为什么我正在开发的当前页面在我不以任何方式直接使用foo类时抛出此错误，我也没有向viewstate设置任何内容。我正在使用回发很多，但就像我说的，我没有在viewstate中存储任何东西等一个整数。

如果相关，我正在使用nhibernate。

我知道为什么我需要将这些类标记为可序列化而不使用？我应该在哪里开始调查？

您是否可能数据绑定此类对象？它显然已经以某种方式进入了页面状态。

Answer 2

我认为你已经启用了一些缓存元素用于查询缓存，或者启用了NHibernate的实际对象图缓存（如果可能的话，使用SysCacheProvider只是HttpRuntime.Cache）。

无论是否使用缓存，我都会建议将每个Domain对象标记为可序列化，因为它在某些时候非常合理，它将通过线路或仅进入ViewState / Session容器。

我的对象是如何进入ASP.NET页面状态的？
