Export-Csv帮助PowerShell

Question

我一直在尝试在Powershell中导入CSV，然后仅导出特定的第2、3和5列，并忽略最后一行。

TestFile.csv：

"1","2","3","4","5"
"1","2","3","4","5"
"1","2","3","4","5"
"1","2","3","4","5"
"1","2","3","4","5"
,,,2,2,2,,,2,,

使用的PowerShell脚本：

Import-Csv '\\DESKTOP-QC1GB24\Allpay DD\Processing\TestFile.csv' -Header (1..5|%{"Column$_"}) |
    Select-Object Column2, Column3, Column5 -SkipLast 1 |
    Export-Csv -Path "\\DESKTOP-QC1GB24\Allpay DD\Completed\New.CSV"

我得到的结果（new.csv）：

#TYPE Selected.System.Management.Automation.PSCustomObject
"Column2","Column3","Column5"
"2","3","5"
"2","3","5"
"2","3","5"
"2","3","5"
"2","3","5"

我面临的问题是它导出临时列标题和数据上方的一些文本。有没有办法排除这种情况？同样喜欢保留文件原始名称的id是否可以用原始文件名+ _new导出？
