控件数组

当页面中有很多控件且控件的ID值只有数字差别时，可以定义数组控件

 

 <table  width="100%"  class="infotable1"  cellspacing="0" cellpadding="0">
          <tr>
             <td>产品型号：</td>
             <td><asp:Label ID="lblSpec1" runat="server" Text=""></asp:Label></td>
             <td><asp:Label ID="lblSpec2" runat="server" Text="" ></asp:Label></td>
              <td><asp:Label ID="lblSpec3" runat="server" Text="" ></asp:Label></td>
               <td ><asp:Label ID="lblSpec4" runat="server" Text="" ></asp:Label></td>
         </tr>
         <tr>
             <td class = "tdr"  > 产品厂商：</td>
             <td  class="tdr2"> <asp:Label ID="lblCom1" runat="server" Text=""></asp:Label></td>
             <td><asp:Label ID="lblCom2" runat="server" Text=""></asp:Label></td>
              <td><asp:Label ID="lblCom3" runat="server" Text=""></asp:Label></td>
               <td><asp:Label ID="lblCom4" runat="server" Text=""></asp:Label></td>
          </tr>
      </table>
