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[i] ; 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:Label font-size="8pt" id="showmsg" runat="server"/> <table width=450 bgcolor=white cellpadding="2" cellspacing="1" class="Grid"> <asp:Label font-size="8pt" id="maininfo" runat="server"/> </table> </center></body></html>  源代码网供稿. |
