根据使用C＃的两个属性将XML转换为DataTable

我有一个XML文件，我想将其制作为DataTable并将其绑定到GridView，但必须根据属性而不是标签从XML文件获取数据。第一个属性是“m”，它代表行索引。另一个属性是“s”，它代表列索引。如果属性没有在一些标签提到的，对于它的默认值是“1”根据使用C＃的两个属性将XML转换为DataTable

输出必须所示GridView这样形式

<asp:GridView id="grdBank" runat="server" AutoGenerateColumns="False" CellPadding="0" > 
    <Columns> 

     <asp:BoundField HeaderText="Repay date" DataField="repay"> 
     <HeaderStyle Font-Bold="True"></HeaderStyle>     
     </asp:BoundField> 

     <asp:BoundField HeaderText="Interest" DataField="interest"> 
     <HeaderStyle Font-Bold="True"></HeaderStyle>     
     </asp:BoundField> 

     <asp:BoundField HeaderText="Penalty interest" DataField="penalty_interest"> 
     <HeaderStyle Font-Bold="True"></HeaderStyle>    
     </asp:BoundField> 

     <asp:BoundField HeaderText="Penalty spread" DataField="penalty_spread"> 
     <HeaderStyle Font-Bold="True"></HeaderStyle>    
     </asp:BoundField> 

     <asp:BoundField HeaderText="Others (CE+CS)" DataField="others"> 
     <HeaderStyle Font-Bold="True"></HeaderStyle>     
     </asp:BoundField> 
    </Columns>

xml文件是
