更新会话值

我在登录时创建了一个会话，在该会话中我已经放置了用户对象。

public sealed class MyContext
{
    [ThreadStatic]
    private static MyContext staticContext = null;
    public HttpContext Context
    {
        get
        {
            return HttpContext.Current;
        }
    }

    private MyContext()
    {
    }
    public static MyContext Current
    {
        get
        {
            MyContext myContext = null;
            HttpContext context = HttpContext.Current;
            if (context != null)
            {
                //it in the Items collection (a per request store)
                if (context.Items.Contains("CONTEXT_KEY"))
                    myContext = context.Items["CONTEXT_KEY"] as MyContext;
                else
                {
                    myContext = new MyContext();
                    myContext.Context.Items["CONTEXT_KEY"] = myContext;
                }
            }
            else if (staticContext != null)
            {
                myContext = staticContext;
            }
            else
            {
                //create a new instance of static context as there is no web request
                staticContext = new MyContext();
                myContext = staticContext;
            }
            return myContext;
        }
    }
    public MyUser User
    {
        get
        {
            MyUser user = null;
            if (Current.Context.Session["LoggedInUser"] != null)
                user = (MyUser)Current.Context.Session["LoggedInUser"];
            else
            {
                user = UserDetail.GetUser(HttpContext.Current.User.Identity.Name);
                if (user == null)
                {
                    //if there is no userID, create anonymous user
                    user = new MyUser();
                    user.IsAnonymous = true;
                    user.UserID = 0;
                }
                //cache in session
                Current.Context.Session["User"] = user;
            }
            return user;
        }
        set
        {
            Current.Context.Session["User"] = value;
        }
    }

}//end class

现在我在整个应用程序中使用这个上下文，我面临的问题是，在一种情况下，如果用户是登录的，同时admin停用该用户，我不能停止用户活动，这是因为用户的信息在会话中。因此，请建议我如何更新特定用户的信息，当管理员停用该用户
