在会话视图对象正在运行的ASP.NET应用程序 [英] View Objects in Session of a Running ASP.NET Application

问题描述

我想我的应用程序转移到外的进程内会话状态，无法找到其会话对象未能序列化 - 在YSOD堆栈跟踪是unrevealing

是否可以查看对象，或至少对象的类型，当前存储在运行的应用程序的会话状态？短调试器附加到正在运行的应用程序，其源$ C ​​$ C可用的，我不知道这是可能的。

我使用Alachisoft的nCache

，所以这里是他们的堆栈跟踪，但它不是有用的：

  System.Web.HttpException（0X80004005）：无法序列化会话状态。在'的StateServer'和'的SQLServer模式，ASP.NET将序列化会话状态的对象，并因此不可序列化对象或对象MarshalByRef不允许。如果类似的序列化是通过在自定义模式自定义会话状态存储做了同样的限制也适用。 ---＆GT; System.Runtime.Serialization.SerializationException：键入System.Web.UI.Control在大会'System.Web程序，版本= 4.0.0.0，文化=中性公钥= b03f5f7f11d50a3a'未标记为可序列。

我必须使用SQL Server会话状态相同的结果：

解决方案

其实你的异常告诉你它到底是什么：你有一个正在被放入用户控件会议的地方，它是没有标记为可序列。

---> System.Runtime.Serialization.SerializationException：键入System.Web.UI.Control在大会'System.Web程序，版本= 4.0.0.0，文化=中性公钥= b03f5f7f11d50a3a'未标记为可序列化。

更新

您可以把一些code在页​​面的OnLoad（或类似），简单地遍历了会议，并转储说出来，这不是太困难的：

 的foreach（在Session.Keys VAR键）
   回复于（的String.Format（{0}：{1}＆LT; BR /＆gt;中，钥匙，会话[关键]）;
 

这不是要找出确切的code /页，但它应该给你一些搜索条件。

I am trying to move my app to out-of-proc session state and can't find which session object is failing to serialize - the YSOD stack trace is unrevealing.

Is it possible to view the objects, or at least the types of objects, currently stored in session state of a running application? Short of attaching a debugger to a running app, and having its source code available, I don't know if this is possible.

I'm using Alachisoft NCache, so here's their stack trace, though it's not helpful:

System.Web.HttpException (0x80004005): Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. The same restriction applies if similar serialization is done by the custom session state store in 'Custom' mode. ---> System.Runtime.Serialization.SerializationException: Type 'System.Web.UI.Control' in Assembly 'System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' is not marked as serializable.

UPDATE

I have the same results using SQL Server session state:

解决方案

Actually your exception tells you exactly what it is: You have a UserControl that is being placed into the Session somewhere and it is not marked as serializable.

---> System.Runtime.Serialization.SerializationException: Type 'System.Web.UI.Control' in Assembly 'System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' is not marked as serializable.

Update

You can put some code in a page OnLoad (or similar) that simply iterates the session and dumps that out, it's not too difficult:

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

That's not going to identify the exact code/page but it should give you some search criteria.
