[原创]Asp.net2.0下利用Global.asax全局文件实现流量分析

一、预览效果：

二：建立数据库脚本：

CREATE TABLE [dbo].[Yp_VisitStat] (
    [iVisitStat_ID] [int] IDENTITY (1, 1) NOT NULL ,
    [sIntoIP] [varchar] (50) COLLATE Chinese_PRC_CI_AS NULL ,
    [dIntoTime] [datetime] NULL 
) ON [PRIMARY]
GO

ALTER TABLE [dbo].[Yp_VisitStat] ADD 
    CONSTRAINT [PK_Yp_VisitStat] PRIMARY KEY  CLUSTERED 
    (
        [iVisitStat_ID]
    )  ON [PRIMARY] 
GO

三、前台Aspx页面代码：

<table class="tableBorder" cellspacing="1" cellpadding="2" width="100%" border="0" style="text-align: center">
        <tr>
        <th style="HEIGHT: 21px" colspan="2" >
            <span style="font-size: 10pt; color: #ffffff">网站综合流量分析</span></th>
        </tr>
        <tr>
        <td class="TableRow2" style="text-align: right; width: 126px;">给合流量统计：</td>
        <td class="TableRow2" style="text-align: left;">
            <asp:Label ID="Label3" runat="server" Text="Label"></asp:Label>&nbsp;&nbsp;
            <asp:Label ID="Label4" runat="server" Text="Label"></asp:Label>
         </td>
        </tr>
        <tr>
        <td class="TableRow2" style="text-align: right; width: 126px;">上月流量统计：</td>
        <td class="TableRow2" style="text-align: left;">
        <asp:Label ID="Label5" runat="server" Text="Label"></asp:Label>&nbsp;&nbsp;
        <asp:Label ID="Label6" runat="server" Text="Label"></asp:Label>
        </td>       
        </tr>
        <tr>
        <td class="TableRow2" style="text-align: right; width: 126px;">本月流量统计：</td>
        <td class="TableRow2" style="text-align: left;">
        <asp:Label ID="Label7" runat="server" Text="Label"></asp:Label>&nbsp;&nbsp;
        <asp:Label ID="Label8" runat="server" Text="Label"></asp:Label>
        </td>       
        </tr>
        <tr>
        <td class="TableRow2" style="text-align: right; width: 126px;">昨日流量统计：</td>
        <td class="TableRow2" style="text-align: left;">
        <asp:Label ID="Label9" runat="server" Text="Label"></asp:Label>&nbsp;&nbsp;
        <asp:Label ID="Label10" runat="server" Text="Label"></asp:Label>
        </td>       
        </tr>
        <tr>
        <td class="TableRow2" style="text-align: right; width: 126px;">今日流量统计：</td>
        <td class="TableRow2" style="text-align: left;">
        <asp:Label ID="Label11" runat="server" Text="Label"></asp:Label>&nbsp;&nbsp;
        <asp:Label ID="Label12" runat="server" Text="Label"></asp:Label>
        </td>       
        </tr>
        <tr>
        <td class="TableRow2" style="text-align: right; width: 126px;">当前在线状况：</td>
        <td class="TableRow2" style="text-align: left;">
        <asp:Label ID="Label13" runat="server" Text="Label"></asp:Label>
        </td>       
        </tr>        
</table>
