主题：合并表

Dim dlg As new OpenFileDialog dlg.Filter = "Excel|*.xls;*.xlsx" If dlg.ShowDialog = DialogResult.OK Then Dim Book As New XLS.Book(dlg.FileName) Dim Sheet As XLS.Sheet = Book.Sheets(0) Tables("成绩").StopRedraw() Dim nms() As String = {"学校代码","单位名称","年级代码","班级","学籍号","考号","姓名"} For n As Integer = 1 To Sheet.Rows.Count -1      Dim bh As String = sheet(n,0).Text      Dim dr As DataRow = DataTables("成绩").Find("考号 = '" & bh & "'")      If dr Is Nothing Then '如果不存在同考号的行         dr =  DataTables("成绩").AddNew()     End If     For m As Integer = 0 To nms.Length - 1         dr(nms(m)) = Sheet(n,m).Value     Next Next Tables("成绩").ResumeRedraw() End If 想法：以考号为关键例，表中已存在则修改其他例为ＥＸＣＬ中最新值，如完全相同则跳过，如新增有行则新增(要实现ＥＸＣＬ修改后完履盖合并进去) 请问上面代码测试当考号不改，而改姓名时还是要新增加一行呢，而不是按同考号覆盖呢，请指导，谢谢

 Dim bh As String = sheet(n,0).Text 

也就是说，能不能先判断下ＥＸＣＬ中考号在第几例

For i As Integer = 0 To Sheet.Cols.Count -1 

我现在问题是如何ＦＯＸ表字段顺序与excl  表字段顺序不对应怎么办

打不开呢
