我正在尝试将我的应用程序移动到进程外会话状态并且找不到哪个会话对象无法序列化 - YSOD 堆栈跟踪未显示。

是否可以查看当前存储在正在运行的应用程序的会话状态中的对象，或者至少是对象的类型？由于没有将调试器附加到正在运行的应用程序并提供其源代码，我不知道这是否可能。

我正在使用 Alachisoft NCache，所以这是他们的堆栈跟踪，虽然它没有帮助：

我使用 SQL Server 会话状态得到了相同的结果：

实际上，您的异常确切地告诉您它是什么：您有一个UserControl被放置到 Session 某处的，它没有被标记为可序列化。

---> System.Runtime.Serialization.SerializationException：在程序集“System.Web，版本=4.0.0.0，文化=中性，PublicKeyToken=b03f5f7f11d50a3a”中键入“System.Web.UI.Control”未标记为可序列化。

您可以将一些代码放在页面 OnLoad （或类似的）中，它只是迭代会话并将其转储出来，这并不难：

foreach(var key in Session.Keys)
   Response.Write(String.Format("{0}: {1}<br/>", key, Session[key]);

这不会识别确切的代码/页面，但它应该为您提供一些搜索条件。
