c# - 从源代码在 sql 查询中传递 Request.QueryString 整数值

Question

我试图在源代码的查询中传递 Request.QueryString 整数值。我该怎么做？

http://localhost:3738/WebSite3/UserDetails.aspx?Id=43

我想在查询中传递 id 的值，即 43

 <asp:SqlDataSource ID="SqlDataSource1" runat="server" 
        ConnectionString="<%$ ConnectionStrings:SLIITComDBConnectionString %>" 

    SelectCommand="SELECT Album.AlbumID, Album.DefaultPhotID, Album.AlbumName, PhotAlbum.Photo FROM Album INNER JOIN PhotAlbum ON Album.DefaultPhotID = PhotAlbum.PhotoID where album.userid= **Request.QueryString[id]** ">

Answer 1

使用QueryStringParameter

<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
    ConnectionString="<%$ ConnectionStrings:SLIITComDBConnectionString %>" 

SelectCommand="SELECT Album.AlbumID, Album.DefaultPhotID, Album.AlbumName, PhotAlbum.Photo FROM Album INNER JOIN PhotAlbum ON Album.DefaultPhotID = PhotAlbum.PhotoID where album.userid= @userid ">
   <SelectParameters>
      <asp:QueryStringParameter Name="userid" Type="String"  QueryStringField="id" />
   </SelectParameters>
</asp:SqlDataSource>
