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>
