那你还不如删除所有表数据，再重新添加数据，效率绝对比你查找数据要来得高

If msgbox("导入更新可以导入客户基础数据和最新的存款余额和年日均余额,是否进行?",65,"提示") = 1 Then
    DataTables("对公客户明细").DataRows.Clear
    Dim Book As New XLS.Book("D:\khdaxt\drgx\dgdrgx.xls")
    Dim Sheet As XLS.Sheet = Book.Sheets(0)
    DataTables("对公客户明细").StopRedraw()
    Dim nms() As String = {"账号","客户号","户名","账户性质","开户日期","存款余额","年日均余额"}
    For n As Integer = 0 To Sheet.Rows.Count -1
        Dim bh As String = sheet(n,0).Text
        'Dim dr As DataRow = DataTables("对公客户明细").Find("账号 = '" & bh & "'")
        Dim dr As DataRow = DataTables("对公客户明细").AddNew
        If dr Is Nothing Then '如果不存在同编号的订单
            dr =  DataTables("对公客户明细").AddNew()
        End If
        For m As Integer = 0 To nms.Length -1
            dr(nms(m)) = trim(Sheet(n,m).Value)
        Next
    Next
    DataTables("对公客户明细").ResumeRedraw()
    msgbox("客户数据导入更新完毕!",64,"提示")
End If
