我们将站点托管在 Windows azure 上，站点在多个实例上运行。由于多个实例，我们使用共享缓存来存储会话值。由于微软即将停止共享缓存，建议使用 redis 缓存来存储会话。我修改了项目以使用 redis 缓存，它适用于大多数页面。我的问题是，我们的站点中有一个非常重要的页面“搜索页面”（我们使用 lucene.net 进行搜索功能），它在会话中存储了大量数据，并且该页面无法正常工作。点击搜索按钮后，在地址栏中显示连接状态很长一段时间，然后进入网站的oops页面。我们正在 DB 中记录错误消息，所以在查看之后我们发现了以下错误消息。

System.Runtime.Serialization.SerializationException: Type 'myWeb.clsSearchCriteria+ContentCriteria' in Assembly 'HelmBriscoeWeb, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is not marked as serializable.

我不确定这是否与我的问题有关，但似乎如果已解决，页面将正常工作。有谁知道为什么会发生此错误以及如何解决？

谢谢

我通过向类添加序列化属性自己解决了这个问题，如下所示。

<Serializable()> _
Public Class clsSearchCriteria

谢谢
