从经典ASP转换为ASP.NET

I have to convert some code from classic ASP to ASP.NET

我必须将一些代码从经典ASP转换为ASP.NET

1) How can I best handle syntax as below, where it seems to fail because the code is inside a tag, and also perhaps because the condition is split over several tags.

1)我如何才能最好地处理如下语法,因为代码在标记内部,似乎失败了,也许因为条件被分成几个标记。

2) Any tools or guidelines that are good on this kind of code?

2)任何有关此类代码的工具或指南?

3) Classic ADO.

3)经典的ADO。

    <li><a<% if "" = myFolder then %> class="selected"<% end if %> href="http://<%= SERVER_NAME %>/"><%= getLocale("Home") %></a></li>
            <% SQL = "SP_TOPNAV  '" & lang & "'"
            Set maNav = conn.execute(SQL)
            do while not maNav.EOF %>
                <li><a<% if maNav(0) = myFolder then %> class="selected"<% end if %> href="http://<%= SERVER_NAME %>/<%= maNav(0) %>"><%= maNav(1) %></a></li>
            <% maNav.MoveNext
            loop
            Set maNav = Nothing %>
            </ul>

ASP.net handles code split between several <%%> tags just fine. The problem lies elsewhere. Please edit your question to include the error message.

ASP.net处理好几个<%%>标签之间的代码分割。问题出在其他地方。请编辑您的问题以包含错误消息。

If your using .net 2.0 look into a asp:repeater that can bind to a datasource, if your using .net 3.5 look into a asp:listview. Those controls give you the ability to iterate through data and generate markup which is essentially what your doing.

如果您使用.net 2.0查看可以绑定到数据源的asp:repeater,如果您使用.net 3.5查看asp:listview。这些控件使您能够迭代数据并生成标记,这基本上就是您的操作。

You can always use ASP.NET's data controls such as Repeater, GridView, DataList to display collections of item. And you can customize their looks by modifying the ItemTemplate. You can also include the rendering conditional inside ItemTemplate too.

您始终可以使用ASP.NET的数据控件(如Repeater,GridView,DataList)来显示项的集合。您可以通过修改ItemTemplate来自定义其外观。您也可以在ItemTemplate中包含渲染条件。

For example:

   <asp:Repeater id="Repeater1" runat="server">

      <HeaderTemplate>
         <table border="1">
      </HeaderTemplate>

      <ItemTemplate>
         <tr>
            <td> <%# Container.DataItem %> </td>
         </tr>
      </ItemTemplate>

      <FooterTemplate>
         </table>
      </FooterTemplate>

   </asp:Repeater>

You can always insert conditional logic inside <%# ... %> text. Or if the logic are complicated, you can code them inside the code behind file and call them from here.

您始终可以在<%#...%>文本中插入条件逻辑。或者,如果逻辑很复杂,您可以在代码隐藏文件中对它们进行编码,并从此处调用它们。

Search for "ASP.NET If inside ItemTemplate" or "ASP.NET Condition in ItemTemplate" for more info.
