您两次调用totable，但您丢弃了第一个实例.上面的行是您的核心问题.抓取返回结果并绑定到该结果.

You''re calling totable twice, but you discard the first instance. The line above is your core issue. Grab that return result and bind to that.

代替这个:

Hi,
Instead of this:

dvTo.ToTable().Rows.Add(dvTo.ToTable().NewRow());

试试这个:

Try this:

dvTo.ToTable().Rows.Add(dvTo.ToTable().NewRow().ItemArray);
