无法序列化会话状态 [英] Unable to serialize the session state

问题描述

当把我的应用程序联机，并试图登录我得到这个错误：

When putting my application online and trying to log in I got this error:

Server Error in '/' Application.
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.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

我和会话在那里做的唯一事情是这样的：

The only thing I do there with Sessions is this:

• 会话[Rechten] =GlobaalAdmin; （例子）


• 会话[gebruikerid] = txtID.Text; （他们登录的ID）


• 并重定向到另一个页面：Response.Redirect的（LoggedIn.aspx，真正的）;


• http://pastebin.com/jZprwA8m （把gebruiker到一个会话）

• Session["Rechten"] = "GlobaalAdmin"; (example)
• Session["gebruikerid"] = txtID.Text; (the ID they log in with)
• And redirect them to another page: Response.Redirect("LoggedIn.aspx",true);
• http://pastebin.com/jZprwA8m (Putting the gebruiker into a session)

有过这个问题，多个主题，但他们都不来帮助我。
一切都在本地工作，但网上没有。

There have been multiple topics about this problem but none of them seem to have helped me. Everything works locally, but online it doesn't.

推荐答案

我们能看到Gebruiker级？有错误似乎很简单。 Gebruiker不作为归咎于被序列化的，因此它不能被放置在会话的StateServer和SQLServer模式。

Can we see the "Gebruiker" class? There error seems straightforward enough. Gebruiker is not attributed as being Serializable therefore it can't be placed in Session for StateServer and SQLServer modes.

编辑：

看着你的链接的code后，是的，这可能是因为类是不可序列。在LINQ生成的类应该是一个部分类，所以你可以实现它标记为可序列化和将sessionState要求，将满足，然后你自己的部分类。

After looking at the code you linked in, yes, it's probably because the class isn't serializable. The LINQ generated class should be a partial class so you can implement your own partial class that marks it as Serializable and the sessionstate requirements will be met then.

[Serializable()]
public partial class Gebruiker { //Lots of stuff }

编辑2：

托马斯，你Gebruiker类可能有一个定义，它看起来像这样现在（或类似的东西）

Thomas, your Gebruiker class probably has a definition that looks like this right now (or something similar)

namespace XYZ
{
   public partial class Gebruiker
}

只要创建一个具有相同的命名空间的另一个类文件，并使用Serializable属性定义类

Just create another class file that has the same namespace and define the class with the Serializable attribute

namespace XYZ
{
  [Serializable()]
  public partial class Gebruiker{}
}

这就是你应该需要在这个文件中。通过这种方式，序列化的属性将不会被当LINQ产生Gebruiker类被创建覆盖。

That's all you should need in this file. This way, the serializable attribute won't be overwritten when the LINQ generated Gebruiker class gets created.
