4楼代码用于获取文件详细信息，你只要标题和艺术家的话，对应编号是21和13。

回复 6# 5i365
true就输出MP3文件，false就不输出。并不会输出“true或false”
你多复制几个MP3文件试试看。


序号13和21是怎么得到的 ？在4楼代码这里加个$a的输出就可以看到了

foreach ($a in -1..255){
  $details=$objfolder.getdetailsof($objfile,$a)  
  if($details -ne ""){"{0}{1}{2}" -f $objfolder.getdetailsof($null,$a),":",$details}
}
复制代码

改为

foreach ($a in -1..255){
  $details=$objfolder.getdetailsof($objfile,$a)  
  if($details -ne ""){"{0}{1}{2}{3}" -f $a,$objfolder.getdetailsof($null,$a),":",$details}
}

$objfolder = $obj.namespace($f)
dir $f -filter *.mp3 | %{
	$objfile = $objfolder.parsename($_.name)
	$artist = $objfolder.getdetailsof($objfile, 13)
	$artist
	$title = $objfolder.getdetailsof($objfile, 21)
	$title
	if($title -match "伴奏" -and $title -notmatch "dj" -and $artist -match "海来阿木"){
$_.fullname
$_.name
}

原来用的是where-object，只输出符合大括号里的条件的内容。
你可以改成foreach-object，这样就在大括号里加if条件。
