主题：合并数据,总是出错,

Dim Book As New XLS.Book("c:\test\订单.xls")   
Dim Sheet As XLS.Sheet = Book.Sheets(0)
Tables("订单").StopRedraw()
'注意以下数组中列名称的顺序,必须和Excel表中的列顺序一致
Dim nms() As String = {"编号","产品","客户","雇员","单价","折扣","数量","日期"}
'注意下面的循环变量从1开始,而不是从0开始,因为Excel表的第一行是标题
For n As Integer = 1 To Sheet.Rows.Count -1
Dim bh As String = sheet(n,0).Text
If DataTables("订单").Find("编号 = '" & bh & "'") Is Nothing Then '如果不存在同编号的订单
Dim r As Row = Tables("订单").AddNew()
For m As Integer = 0 To nms.Length - 1
r(nms(m)) = Sheet(n,m).Value
Next
End If
Next
Tables("订单").ResumeRedraw()

我有个文件是csv格式的;用此方法合并数据,总是出错,请问这是什么原因?
