列出所有活动的 ASP.NET 会话 [英] List all active ASP.NET Sessions

问题描述

如何列出(并遍历)所有当前的 ASP.NET 会话?

How can I list (and iterate through) all current ASP.NET sessions?

推荐答案

您可以在 global.asax 事件 Session_Start 和 Session_End(仅在进程内设置中)中收集有关会话的数据:

You can collect data about sessions in global.asax events Session_Start and Session_End (only in in-proc settings):

private static readonly List<string> _sessions = new List<string>();
private static readonly object padlock = new object();

 public static List<string> Sessions
 {
       get
       {
            return _sessions;
       }
  }

  protected void Session_Start(object sender, EventArgs e)
  {
      lock (padlock)
      {
          _sessions.Add(Session.SessionID);
      }
  }
  protected void Session_End(object sender, EventArgs e)
  {
      lock (padlock)
      {
          _sessions.Remove(Session.SessionID);
      }
  }

你应该考虑使用一些并发集合来降低同步开销.ConcurrentBag 或 ConcurrentDictionary.或者 ImmutableList

You should consider use some of concurrent collections to lower the synchronization overhead. ConcurrentBag or ConcurrentDictionary. Or ImmutableList
