主题：[求助]导出数据

在写入数据时的这新代码中加入判断日期字段的语句,如果为空,则在Excel对应单元写入空值即可.

For r As Integer = 0 To dt.Rows.Count - 1

    For c As Integer = 0 To nms.length -1
     if nms(c)="日期" then

       if dt.rows(r).isnull(nms(c)) then
          Sheet(r +1, c).Value =nothing

       else

          Sheet(r +1, c).Value = dt.rows(r)(nms(c))

      end if

      else

       Sheet(r +1, c).Value = dt.rows(r)(nms(c))
    end if

    Next
Next
