Download the latest taglib: http://download.banshee.fm/taglib-sharp/
#Create a variable for the tag-lib dll file

$taglib = "C:\PowerShell\taglib\libraries\taglib-sharp.dll"

#Load it into Powershell

[system.reflection.assembly]::loadfile($taglib)

#Find an MP3 and either assign it to a variable or put it's name into the create field

$media = [taglib.file]::create("e:\test\body.mp3")

#Now you can view, edit, and save ID3 information

PS E:\test> $media.properties

回复 2# PowerShell

英语不行，看不懂。能否帮忙写一个可以直接拿来执行的？我试试，然后体会一下。
