Question

我正在编写一个Web应用程序，该部分包含字符串列表，并将它们绑定到asp.net中继器。以下是执行此操作的代码区域的片段：

stationinstructions.aspx.vb

'listOfFiles is a list of strings
    Me.rptFiles.DataSource = listOfFiles
    Me.rptFiles.DataBind()

stationinstructions.aspx

<asp:Repeater ID="rptFiles" runat="server">
                  <HeaderTemplate>
                       <ul>
                  </HeaderTemplate>
                  <ItemTemplate>
                              <div id="color1"><li><a href="javascript:getfile('<%# Eval("Name") %>')"><%# Eval("Name") %></a></li></div>
                              <div id="color2"><b p><%# Eval("Name") %></b></div>
                  </ItemTemplate>
                  <FooterTemplate>
                       </ul>
                  </FooterTemplate>
            </asp:Repeater>

我确信我在配置文件中使用了正确版本的.net框架。这是我经过“ Me.rptFiles.DataBind（）”时得到的确切错误消息：

Unable to find the requested .Net Framework Data Provider.  It may not be installed.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

   System.Web.UI.Control.PreRenderRecursiveInternal() +160

我应该从哪里开始寻找导致错误的原因？

（vb）数据绑定时出现错误“无法找到请求的.Net Framework数据提供程序”
