[求助]Excel数据导入前的校验，帮忙改下代码，谢谢 - 专家坐堂 - Foxtable(狐表) - 新一代数据库软件，完美融合Access、Foxpro、Excel、vb.net之优势，人人都能掌握的快速软件开发工具!

想在Excel数据导入时，做一下校验，是否包含那几项，但是老是提示有问题，不知大怎么处理了，望指教，谢谢！

Dim dlg As New OpenFileDialog

dlg.Filter = "Excel文件|*.xls"

dlg.MultiSelect = False '不允许选择多个文件

If dlg.ShowDialog =DialogResult.OK Then

Dim Book As New XLS.Book(dlg.FileName)

Dim Sheet As XLS.Sheet = Book.Sheets(0)

Dim nms() As String = {"姓名","身份证号码","单位","培训日期","培训类型","培训项目"}

Dim idds() As String

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

idds(n) = Sheet(0,n).Value

Dim iscontains = False

For Each nm As String In nms

Output.Show(nm)

If array.indexof(idds, nm) < 0 Then

iscontains = False

Exit For

End If

If iscontains = False Then

messagebox.show("所选文件部分必选字段缺少,无法导入!")

Return "所选文件部分必选字段缺少,无法导入!"

End If
