Question

我知道哪位用户符合以下的法典:

Session["loggedInUserId"] = userId;

The question I have is how do I know what users are logged in so that other users can see what users are currently logged in.

换言之,我能够积极参加所有“挂牌的InUserId”会议?

我曾尝试过大草塔那兹解决办法,但我使用了另一种方法,对我只做了罚款。

private List<String> getOnlineUsers()
    {
        List<String> activeSessions = new List<String>();
        object obj = typeof(HttpRuntime).GetProperty("CacheInternal", BindingFlags.NonPublic | BindingFlags.Static).GetValue(null, null);
        object[] obj2 = (object[])obj.GetType().GetField("_caches", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(obj);
        for (int i = 0; i < obj2.Length; i++)
        {
            Hashtable c2 = (Hashtable)obj2[i].GetType().GetField("_entries", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(obj2[i]);
            foreach (DictionaryEntry entry in c2)
            {
                object o1 = entry.Value.GetType().GetProperty("Value", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(entry.Value, null);
                if (o1.GetType().ToString() == "System.Web.SessionState.InProcSessionState")
                {
                    SessionStateItemCollection sess = (SessionStateItemCollection)o1.GetType().GetField("_sessionItems", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(o1);
                    if (sess != null)
                    {
                        if (sess["loggedInUserId"] != null)
                        {
                            activeSessions.Add(sess["loggedInUserId"].ToString());
                        }
                    }
                }
            }
        }
        return activeSessions;
    }

该网页上列出了解决办法。列出所有活跃的协会。 NET Sessions

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

public static List<string> Sessions
{
        get
        {
            lock (padlock)
            {
                if (_sessionInfo == null)
                {
                    _sessionInfo = new List<string>();
                }
                return _sessionInfo;
            }
        }
  }

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

基本上,它只是把会议记录在一份清单中,你可以用来查找有关资料。能够真正将任何东西储存到你真正想要的东西——用户名称或任何东西。

我在ASP .net层没有任何东西可以做到?

foreach (var item in Session.Contents)
{Response.Write(item + " : " + Session[(string)item] + "<br>");}
