Answer 1

这听起来像是您尝试运行应用程序的服务器，默认情况下没有启用会话状态。

您可以通过web.config按应用程序启用此功能，只需将其放在文件中即可：

<system.web>
    ..
    <sessionState mode="InProc" />
</system.web>

这将启用存储会话状态（服务器端）的处理方法中的默认值。

如果这没有帮助，可能会指出另一个问题，但我们需要查看完整的异常信息＆amp;堆栈跟踪。

I think my pure MVC project (that worked in Test environment) was too simple and may not have forced the MVC framework to require TempData and SessionState, so that's how I'll explain it away ;-)

如何在asp.net mvc中传递数据到控制器？
