主题：导入excel中所有的sheet内容

就是如果这个excel中包括了多个sheet，每个sheet的列名格式都是一样的。

循环逐个sheet导入Tables("订单").StopRedraw()

Systemready = False
Dim mr As Row = Tables("库存管理界面_table29").AddNew()
mr.save
Dim App As New MSExcel.Application
try
    Dim tsxx As WinForm.Label = e.Form.Controls("Label73")
    tsxx.text = "正在导入OEM IN 直销序列号请耐心等待!"
    Dim Wb As MSExcel.Workbook = App.WorkBooks.Open("D:\直销序列号.xls")
    For Each ws As object In Wb.worksSheets
        Tables("库存管理界面_table29").DataTable.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 ra = ws.UsedRange
        Dim nms() As String = {"采购订单号","存货编码","存货名称","SN","MAC"}  '如果execl里面的列名或者顺序与数组的不一致,该如何报错提醒用户要导入的execl格式不对呢
        Dim flag = False
        For i As Integer = 0 To nms.length-1
            If nms(i) <> ws.cells(1, i+1).text Then
                msgbox(ws.name & " 格式不匹配")
                flag = True
                Exit For
            End If
        Next
        If flag Then Continue For
        '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 = 2 To ra.Rows.Count
            Dim xlh As String = ws.cells(n,4).Text    '序列号----SN,xlh
            If DataTables("库存明细表").SQLFind("SN = '" & xlh & "'") Is Nothing Then '如果不存在同编号的计划表
                Dim r As Row = Tables("库存管理界面_table29").AddNew()
                r("工单行号") = "ZXSN" & r("_identify")
                r("订单行号") = "ZXSN" & r("_identify")
                r("库位类别") = "30"
                r("数量") = 1
                r("订单号") = ws.cells(n,1).Value
                r("生产订单号码") = "ZX" & r("订单号")
                r("物料编码") = ws.cells(n,2).Value
                r("物料名称") = ws.cells(n,3).Value
                r("SN") = ws.cells(n,4).Value
                r("MAC") = ws.cells(n,5).Value
                r("出库完成时间") = Date.Today
                r("货运单号") = "直销发货"
                r.Save
            End If
        Next
    Next
    Tables("库存管理界面_table29").DataTable.ResumeRedraw()
    DataTables("库存明细表").SQLDeleteFor("SN is null")
    DataTables("库存明细表").RemoveFor("SN is null")
   
    tsxx.text = "请导入OEM IN 直销序列号!"
    MessageBox.show("OEM IN直销序列号已导入完成","导入完成",MessageBoxButtons.OK,MessageBoxIcon.Information)
catch ex As exception
finally
    app.quit
End try
Systemready = True

万一某个sheet是空表呢？这样不就认为格式不对。空表应该不算才行。

If ra.rows.count>0 OrElse ra.columns.count>0 Then '不是空表

关闭项目，重新打开，重新测试。

 

测试时，去掉 Systemready = False

按照你说的做好像也没用，请再帮忙排查一下。

加上红色代码
