azure - Windows azure redis缓存迁移问题

Question

我们在 Windows azure 上托管我们的网站，该网站在多个实例上运行。由于多个实例，我们使用共享缓存来存储 session 值。由于微软即将停止共享缓存并建议使用redis缓存来存储session。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，我们的网站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)，该页面在 session 中存储大量数据，但该页面无法正常工作。点击搜索按钮后，地址栏中长时间显示连接状态，并转到网站的oops页面。我们正在数据库中记录错误消息，因此查看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，但似乎如果此问题得到解决，页面将正常工作。有谁知道为什么会发生此错误以及如何修复它？

谢谢

我自己通过向类添加序列化属性解决了这个问题，如下所示。

<Serializable()> _
Public Class clsSearchCriteria

谢谢
