aspx 页面错误传递存储过程(sql) ASP.NET (C#)

Question

我是 asp 编程新手。我在此页面中使用了直接 SQL 命令并且程序是运行正确但是当我将命令更改为存储过程并按如下方式定义它们时，出现如下所述的错误。

ASPX 标记：

    <asp:SqlDataSource ID="SqlDataSourceTech" runat="server" 
        ConnectionString="<%$ ConnectionStrings:constr %>" 
        SelectCommand="usp_get_technical_data"
        UpdateCommand="usp_update_technical_data" 
        SelectCommandType = "StoredProcedure" 
        UpdateCommandType ="StoredProcedure">

        <SelectParameters>
        <asp:ControlParameter ControlID="LblTowerNo" Name="tower" PropertyName = "Text" Type = "String"/>
           </SelectParameters>
        <UpdateParameters>
            <asp:Parameter Name="type" Type="String" />
            <asp:Parameter Name="extension" Type="String" />
            <asp:Parameter Name="insulator" Type="String" />
            <asp:Parameter Name="aviation_lamp" Type="String" />
            <asp:Parameter Name="pilot" Type="String" />
            <asp:Parameter Name="t_start" Type="DateTime" />
            <asp:Parameter Name="t_complete" Type="DateTime" />
            <asp:Parameter Name="tower" Type="String" />
        </UpdateParameters>
    </asp:SqlDataSource>

错误：

Server Error in '/' Application.

Answer 1

检查行：

ConnectionString="<%$ ConnectionStrings:constr %>"

如果 ConnectionString 里面有双引号，请尝试对参数使用单引号，例如：

ConnectionString='<%$ ConnectionStrings:constr %>'

最终再次仔细检查 post 代码周围的 before/after 代码。
