如您所知,Excel已有1048574行。如何在代码下方导出超过一百万行?如果达到最大行数,那么如何继续循环中的新工作表?如何改编? 我发现好powershell functions之后我正在搜索一些。

使用您对当前行号的现有知识来确定何时达到最大行,然后移至新工作表。

$dirToAudit = Get-ChildItem -Path "C:\inetpub" -recurse | Where { $_.psIsContainer -eq $true }
$maxRow = 1048576
$intRow = 1
$intNextSheet = 2
foreach ($dir in $dirToAudit)
{
$colACL = Get-Acl -Path $dir.FullName
foreach ($acl in $colACL)
{
$fileNameRow = $ws.CreateRow($intRow)
$fileNameRow.CreateCell(0).SetCellValue($dir.FullName)
$intRow++
if ($intRow -eq $maxRow)
{
$ws = $wb.CreateSheet("Company_NTFS_Permissions" + $intNextSheet);
$intNextSheet++
$intRow = 0
}
foreach ($accessRight in $acl.Access)
{
$values = $ws.CreateRow($intRow)
$values.CreateCell(1).SetCellValue($($AccessRight.IdentityReference).ToString())
$values.CreateCell(2).SetCellValue($($AccessRight.FileSystemRights).ToString())
$values.CreateCell(3).SetCellValue($($AccessRight.AccessControlType).ToString())

}
}
$fs = new-object System.IO.FileStream("C:\DRIVERS\test.xlsx",[System.IO.FileMode]'Create',[System.IO.FileAccess]'Write')
$wb.Write($fs);
$fs.Close()
这里重要的一点:
if ($intRow -eq $maxRow)
{
$ws = $wb.CreateSheet("Company_NTFS_Permissions" + $intNextSheet);
$intNextSheet++
$intRow = 0
}
每次$intRow
递增后运行,检查是否已达到$maxRow
。如果是这样,它将移动到带有编号名称的新工作表,并从第一行重新开始。
