asp.net应用程序中的会话状态enableSessionState问题
生产环境出现如下错误
仅当在配置文件或 Page 指令中将 enableSessionState 设置为 true 时，才能使用会话状态。另请确保应用程序配置中的configuration\system.web\httpModules 部分中包含System.Web.SessionStateModule 或自定义会话状态模块。
到目前为止，我已尝试过以下操作
- 检查
machine.config和web.config，两者都有enableSessionState="true" - 添加
enableSessionState="true"到web.config中的页面 - 状态模块也添加到
- 甚至尝试设置
enableSessionState="true “在页面指令中
注意：当我尝试在开发环境中调试代码，一切正常。
谁能帮我解决这个问题，我只是想不出解决办法。
I get the following error in the production environment
Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the configuration\system.web\httpModules section in the application configuration.
The following things I have tried as of now
- Checked
machine.configandweb.config, both haveenableSessionState="true" - Added
enableSessionState="true"to pages inweb.config - State module is also added in
<httpmodules>section - Even tried setting
enableSessionState="true"in page directive
Note: When I try to debug the code in Dev environment, everything works fine as it should.
Can anyone help me out getting over this issue, I just can't figure out a way out of it.

您的会话状态配置是什么样的？您可能希望设置为使用 inproc 会话处理。

What does your session state config look like? You probably want to be set up to use inproc session handling.

我知道这是一个迟到的回复，但我只想补充一下我如何解决同样的问题。
首先我想强调，我使用的是 Web 表单，而不是 MVC - 这可能不适用于 MVC。
我创建了一个包含类 ContactUser 的 Web 表单，并创建了自己的构造函数，因此它看起来像：
public ContactUser(String to, bool isUser)
{
...
}
在此我尝试访问会话变量：
String user = Session["username"]
事实证明，您不能使用会话状态类的构造函数，但您可以在您编写的其他函数以及 protected void Page_Load(object sender, EventArgs e) 过程中使用它。因此，一旦我将会话状态从构造函数移到页面加载过程中，一切就正常了:)！
希望这对遇到同样问题的人有所帮助：D！
I know this is a late response but I just want to add how I fixed the same problem.
First I want to emphasize that I'm using web forms, not MVC - this may not work for MVC.
I created a web form that contained the class ContactUser and I created my own constructor so it looked like:
public ContactUser(String to, bool isUser)
{
...
}
And in this I tried to access a session variable:
String user = Session["username"]
It turns out that you CANNOT use the session state in the constructor of a class, but you can use it in other functions that you write and in the protected void Page_Load(object sender, EventArgs e) procedure. So once I moved session state out of the constructor into the page load procedure everything worked :)!
Hope this helps anyone that runs into the same problem :D!
