启动后台线程可以用下面的语句：
CheckOnline online=new CheckOnline();
用户可以将它放到GLOBAL。ASAX中，我是没有了，只放到了一个ASPX文件中做简单的测试。如下
//start.aspx
<%@ Page Language="c#" autoEventWireup=true Debug="true" %>
<%@ Assembly Name="Soholife" %>
<%@Import Namespace="System"%>
<%@Import Namespace="Soholife"%>
<%@Import Namespace="System.Collections"%>
<script runat="Server" Language="C#">
void Page_Load(Object sender, EventArgs args)
{
CheckOnline online=new CheckOnline();
}
</script>
<html><head>
<style type="text/css">
td{font-size:12;}
.bgcolor{background:#ffffcc;}
</style>
</head>
<body><center>
</center></body></html>
而我们还需要一个程序来显示当前在线拥护的数据，程序如下：
//online.aspx
<%@ Page Language="c#" autoEventWireup=true Debug="true" %>
<%@ Assembly Name="Soholife" %>
<%@Import Namespace="System"%>
<%@Import Namespace="Soholife"%>
<%@Import Namespace="System.Collections"%>
<script runat="Server" Language="C#">
void Page_Load(Object sender, EventArgs args)
{
OnLineUser temp= new OnLineUser();
ArrayList alluser =temp.alluser;
string str="";
str = "<tr bgcolor=#ffff99>";
str = "<td width=100 align=center class=coolbar>用户</td>";
str = "<td align=center width=150 class=coolbar>登陆时间</td>";
str = "<td align=center width=150 class=coolbar>最近时间</td>";
str = "<td width=100 height=20 class=coolbar>当前位置</td>";
str = "</tr>";
for ( int i = 0 ; i < alluser.Count ; i )
{
Soholife.User tempuser=(Soholife.User)alluser
;
str = "<tr bgcolor=white>";
str = "<td>" tempuser.name "</td>";
str = "<td>" tempuser.lasttime "</td>";
str = "<td>" tempuser.curtime "</td>";
str = "<Td>" tempuser.iswhere "</td>";
str = "</tr>";
}
maininfo.Text=str;
}
</script>
<html><head>
<style type="text/css">
td{font-size:12;}
.bgcolor{background:#ffffcc;}
</style>
<script language=javascript>
function openwindow(url,w,h)
{
window.open(url,"","toolbar=no,menubar=no,directories=no,status=yes,width=" w ",height=" h ",scrollbars=yes,resizable=yes");
return false;
}
</script>
</head>
<body bgcolor="#ccffcc"><center>
<Br>
<table width=450 bgcolor=white cellpadding="0" cellspacing="0" style="border:none";>
<Tr><td colspan=2 align=center class=bar>当前在线用户</td></tr>
</table><br>
<asp
abel font-size="8pt" id="showmsg" runat="server"/>
<table width=450 bgcolor=white cellpadding="2" cellspacing="1" class="Grid">
<aspabel font-size="8pt" id="maininfo" runat="server"/>
</table>
</center></body></html>
