asp編程案例:用ASP完成對(duì)MP3曲目信息的設(shè)置

    先簡(jiǎn)單說(shuō)一下MP3的ID3 標(biāo)記，因?yàn)橹饕�是操作這個(gè)玩意
MP3最開(kāi)始的時(shí)候沒(méi)有我們今天看到的那樣，有歌手、年代，專(zhuān)集等等信息
只有一些簡(jiǎn)單的參數(shù)如yes/no來(lái)表示是不是privated或者copyrighted等信息，這樣對(duì)MP3的相關(guān)工作帶來(lái)了很多不便，1996年的時(shí)候有個(gè)老外提出來(lái)在每個(gè)MP3后面追加一段數(shù)據(jù)，用以存放上述的那些信息，后來(lái)就發(fā)展成為id3 v1 據(jù)我所知的現(xiàn)在已經(jīng)到1.1了，具體的還是自己去查一下吧
還是老習(xí)慣，用metadata來(lái)引入DLL，我以前有文章貼過(guò)的，不知道的請(qǐng)自己去查
看代碼
