无法序列化会话状态;部署ASP时出现错误.网的网站

本文关键字：错误 网站 ASP 序列化 会话状态 部署 | 更新日期: 2023-09-27 18:15:35

此代码在我的本地系统中运行良好，但在部署后访问站点时抛出以下错误。它的会话状态没有在应用程序的任何地方声明。请告诉我如何处理这件事。

无法序列化会话状态。在"StateServer"answers"SQLServer"模式下，ASP. sqlNET将序列化会话状态对象，因此不可序列化的对象或MarshalByRef对象是不允许的。如果在' custom '模式下由自定义会话状态存储完成类似的序列化，则适用相同的限制。描述:在执行当前web请求期间发生了未处理的异常。请查看堆栈跟踪以获得有关错误及其在代码中的起源的更多信息。

Exception Details: System.Web.HttpException: 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.

如果您部署到单个服务器，只需确保SessionMode设置为InProc。该设置可能在部署过程中丢失。

当你想使用多个服务器时，你必须确保你放入会话的所有内容都是可序列化的。

从错误中，您现在正在会话中存储System.Data.DataView。我不确定这是否明智。

由于您正在使用进程外会话数据存储，这将要求您添加到session的任何类型都是Serializable。这意味着您不能将任何类添加到Session并期望它能够顺利工作。许多第三方类和BCL类是不可序列化的，因此不能直接使用。

这是因为您要么使用StateServer或Sql Server模式来存储会话对象和DataView是不可序列化的。而不是只是使用InProc状态服务器，如Henk建议，我宁愿只是把可序列化的对象在Session，如果你不想意外时，asp.net工作进程回收和所有的会话对象丢失。
