思路:1.文件上传的时候DB记录文件路径。

           2.default.aspx增加datalist控件设计模版

前台如:

<asp:DataList ID="DataList1" runat="server" Height="30px" RepeatColumns="1" 
                        Width="705px" CssClass="style4">
                        <ItemTemplate>
                            <table cellpadding="0" cellspacing="0" class="" 
                                style="width:644px; height: 54px;">
                                <tr>
                                    <td align="left" colspan="2" 
                                        style="padding-right: 0px; padding-left: 0px; padding-bottom: 0px; padding-top: 1px; height: 35px; ">
                                        &nbsp;<asp:Image ID="Image1" runat="server" Height="248px" 
                                            ImageUrl='<%# DataBinder.Eval(Container.DataItem,"Imgurl") %>' 
                                            Width="428px" />
                                    </td>
                                </tr>
                                <tr>
                                    <td align="left" class=" fist_lines4" 
                                        style="padding-right: 0px; padding-left: 0px; padding-bottom: 0px; padding-top: 3px; ">
                                        &nbsp;&nbsp;图片名称:</td>
                                    <td align="left" class="tdd-gray-b fist_lines2" 
                                        style="padding-right: 0px; padding-left: 0px; padding-bottom: 0px; padding-top: 3px; height: 29px;">
                                        &nbsp;
                                        <asp:Label ID="Label4" runat="server" Font-Bold="True" Font-Size="10pt" 
                                            Text='<%# DataBinder.Eval(Container.DataItem,"imgname") %>'></asp:Label>
                                    </td>
                                </tr>
                                <tr>
                                    <td align="left" class=" fist_lines4" 
                                        
                                        style="padding-right: 0px; padding-left: 0px; padding-bottom: 0px; padding-top: 3px; " 
                                        bgcolor="#CCFFFF">
                                        &nbsp; 设备名称:</td>
                                    <td align="left" class=" fist_lines4" 
                                        
                                        style="padding-right: 0px; padding-left: 0px; padding-bottom: 0px; padding-top: 3px" 
                                        bgcolor="#CCFFFF">
                                        &nbsp;
                                        <asp:Label ID="Label5" runat="server" Font-Size="10pt" 
                                            Text='<%# DataBinder.Eval(Container.DataItem,"Sbname") %>' 
                                            ForeColor="#006600"></asp:Label>
                                    </td>
                                </tr>
                                <tr>
                                    <td align="left" class=" fist_lines4" 
                                        style="padding-right: 0px; padding-left: 0px; padding-bottom: 0px; padding-top: 3px; ">
                                        &nbsp; 上传人员:&nbsp;</td>
                                    <td align="left" class=" fist_lines4" 
                     枯困                   style="padding-right: 0px; padding-left: 0px; padding-bottom: 0px; padding-top: 3px">
                                        &nbsp;
                                        <asp:Label ID="Label6" runat="server" Font-Size="10pt" 
                                            Text='<%# DataBinder.Eval(Container.DataItem,"Sysemp") %>'></asp:Label>
                                    </td>
                                </tr>
                            </table>
                        </ItemTemplate>
                  扒并  </asp:DataList>

后台:

 private void imgdata(string sbid)
    {
        没此念Label7.Text = sbid;
        sql = "select * from sb_imgupload_t where sbid='" + sbid + "' ";
        ds = MySqlHelper.ExecuteDataset(constr, sql);
        if (ds.Tables[0].Rows.Count > 0)
        {
            
            DataList1.DataSource = ds.Tables[0];
            DataList1.DataBind();
        }
        else
        {
            DataList1.DataSource = null;
            DataList1.DataBind();
            
        }
    }

效果:
