在Global.ascx中做,这样是最简单的,但是统计太粗糙.如果想要精细的统计,得用别的办法了.

protected void Application_Start(Object sender, EventArgs e)
        {
            try
            {
                long lCount = 0;
                StreamReader sdr = new StreamReader(Server.MapPath("App_Data/count.txt"));
                string strCount = sdr.ReadLine();
                if (strCount != null)
                {
                    if (strCount.Trim().Replace(((char)13).ToString(), "") != "")
                    {
                        lCount = long.Parse(strCount);
                    }
                }
                sdr.Close();
                Application.Lock();
                Application["counter"] = lCount;
                Application.UnLock();
            }
            catch { }
        }
 
		protected void Session_Start(Object sender, EventArgs e)
		{
            try
            {
                if (Request.ServerVariables["URL"].IndexOf("admin") == -1)
                {
                    long lCount = 0;
                    lCount = long.Parse(Application["counter"].ToString()) + 1;
                    StreamWriter sw = new StreamWriter(Server.MapPath("App_Data/count.txt"));
                    sw.Write(lCount.ToString());
                    sw.Close();
                    Application.Lock();
                    Application["counter"] = lCount;
                    Application.UnLock();
                }
            }
            catch { }
		}

至于在线人数,在session_start里加入session判断就行了.有session的为登陆,没有的别为游客.
