There is nothing like session container , so you can set it as null
没有像会话容器那样的东西，因此您可以将其设置为 null
but rather you can set individual session element as null or ""
而是您可以将单个会话元素设置为 null 或 ""
like Session["userid"] = null;
喜欢 Session["userid"] = null;

There are many ways to nullify session in ASP.NET. Session in essence is a cookie, set on client's browser and in ASP.NET, its name is usually ASP.NET_SessionId. So, theoretically if you delete that cookie (which in terms of browser means that you set its expiration date to some date in past, because cookies can't be deleted by developers), then you loose the session in server. Another way as you said is to use Session.Clear()method. But the best way is to set another irrelevant object (usually nullvalue) in the session in correspondance to a key. For example, to nullify Session["FirstName"], simply set it to Session["FirstName"] = null.
在 ASP.NET 中有很多方法可以使会话无效。Session本质上是一个cookie，设置在客户端的浏览器上，在ASP.NET中，它的名字通常是ASP.NET_SessionId. 因此，理论上如果您删除该 cookie（就浏览器而言，这意味着您将其到期日期设置为过去的某个日期，因为开发人员无法删除 cookie），那么您将丢失服务器中的会话。你说的另一种方法是使用Session.Clear()方法。但是最好的方法是null在会话中设置另一个不相关的对象（通常是值）与一个键相对应。例如，要使 无效Session["FirstName"]，只需将其设置为Session["FirstName"] = null。
