在ASP.NET中序列化会话状态 [英] serializing session state in asp.net
问题描述
我正在尝试在我们的nopcommerce 1.9安装中将会话状态存储在SQL中，而不是InProc中.当我对web.config进行必要的更改时，出现此错误:
I'm trying to store session state in SQL instead of InProc in our nopcommerce 1.9 install. When I make the requisite changes to the web.config I get this error:
"/"应用程序中的服务器错误.
Server Error in '/' Application.
无法序列化会话状态.在"StateServer"中，在"SQLServer"模式下，ASP.NET将序列化会话状态对象，结果是不可序列化的对象或MarshalByRef对象是不允许.如果序列化类似，则适用相同的限制由自定义会话状态存储以自定义"模式完成.
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.

请告诉我，我不需要序列化Nopcommerce中的每个对象来执行此操作！
Somebody PLEASE tell me I don't need to serialize every object in Nopcommerce to do this!
推荐答案
作为例外，您的类型
NopSolutions.NopCommerce.BusinessLogic.Categories.Category
不可序列化.我不知道该类型的实现，但是您可以尝试使用 [Serializable] 属性装饰该类型.
is not serializable. I dont know the implementation of that type but you can try to decorate the type with the [Serializable] attribute.
如果您不能执行此操作，则只需将对象的ID写入会话即可.
如果要将会话存储在sql服务器中，则写入会话的每个对象都必须可序列化.
If you want your session stored in sql server, every object your write into your session needs to be serializable.
