当我尝试编辑现有的Excel文件时，我不断收到以下错误消息：

指数超出范围。 必须是非负数，小于集合的大小。“＆vbCrLf＆”参数名称：索引

码：

Dim file As New FileInfo(Path) Dim objXLApp = New ExcelPackage(file) Dim objXLWs = objXLApp.Workbook.Worksheets("DiscreteAlarms") Dim aantal_Rows As Integer = objXLWs.Dimension.Rows pgb_alarm_check_File2.Maximum = aantal_Rows Dim i As Integer For i = 2 To aantal_Rows Dim Alarm_Text = objXLWs.Cells(i, 3).Value If Alarm_Text = "" Then objXLWs.Cells(i, 3).Style.Fill.BackgroundColor.SetColor(Color.Red) End If pgb_alarm_check_File2.Value = i Next objXLApp.Save()
