Question

我已将MVC应用程序部署到Web服务器，并在我的某个按钮上发现它引发SessionStateTempDataProvider class requires session state to be enabled.错误。

错误解释了很多，我需要启用SessionStateModule并将该标记添加到我的Web.config as explained here。

但是当我编辑Web.config并再次运行时，会抛出相同的错误。我必须添加<module>属性，因为我的配置文件中没有包含一个属性。所以我不确定我的格式是否已关闭。模块属性已添加到<system.webServer>

内

<modules>
    <add name="SessionStateModule" type="System.Web.SessionState.SessionStateModule" />
  </modules>

问题：

如何从Web.config文件启用会话状态？

Web.config文件：

<?xml version="1.0" encoding="utf-8"?>

原来的问题是，与本地IIS实例相比，服务器IIS上没有设置会话状态类型。

将会话状态属性设置为＆＃34; InProcess＆＃34;修正了错误：
