数据是数据库里面动态读取的。
看代码：<table>
                    <!--展团靓盘logo开始-->
                    <tr>
                        <asp:DataList ID="dtlZhanTuanLogo" runat="server" RepeatColumns="8">
                            <ItemTemplate>
                         <td>
                                    <%--<%# strShow(Convert.ToString(Eval("ID")),Convert.ToString(Eval("F_CLink")),Convert.ToString(Eval("F_CDec"))) %>--%>
                                    <img src="<%# Eval("F_CLink") %>" alt="<%# Eval("F_CDec") %>"/>
                        </td> 
                       </ItemTemplate>
