-- 作者:ufo20085 -- 发布时间:2020/6/20 17:16:00 -- 导入一个Excel时提示“没有足够的内存继续执行程序” 一个Excel数据,大约4万行,14兆左右。 导入到foxtable里,居然提示“没有足够的内存继续执行程序”,导入失败。 以下是导入的代码: Dim dlg As New OpenFileDialog dlg.Filter = "Excel文件|*.xls;*.xlsx" If dlg.ShowDialog =DialogResult.OK Then Dim t As Table = Tables("整体通关时间分析列表展示数据") \'t.ResumeRedraw() t.StopRedraw() Dim App As New MSExcel.Application try Dim Wb As MSExcel.WorkBook = App.WorkBooks.Open(dlg.FileName) Dim Ws As MSExcel.WorkSheet = Wb.WorkSheets(1) Dim Rg As MSExcel.Range = Ws.UsedRange Dim arg = rg.value For n As Integer = 2 To rg.Rows.Count Dim r As DataRow = t.DataTable.AddNew() For i As Integer = 1 To rg.Columns.count Dim cname As String = arg(1,i) If cname > "" AndAlso t.Cols.Contains(cname) Then If cname > "" AndAlso t.Cols.Contains(cname) Then If t.Cols(cname).IsDate AndAlso arg(n,i) = "" Then r(cname) = Nothing Else r(cname) = arg(n, i) End If End If End If Next Next catch ex As exception msgbox(ex.message) MessageBox.Show("导入失败!","恭喜!") finally t.ResumeRedraw() app.quit End try End If
