Čtečka tagů hudby ve VB.NET

Nájdeš si nejakú knižnicu na čítanie tagov a použiješ ju. Napr. čo som pogooglil, tak TagLib# by mala byť použiteľná.

jak na to ?

tohle není vb.net

kam mám hodit ten soubor abych ho mohl importovat ?

To nemáš nikam hodit. To je příklad použití.

jasně, ale jak mám importovat tu knihovnu "taglib" a "gnome"

Důležitý je ten taglib a ten máš hned v prvním odkazu.

já to chápu ale jak ! stáhnu si ten ten zip ( poslední verzi) rozbalím to a co s tím dál ?? to nevím kam to mám nakopírovat ? nebo jak udělat aby mi to při importu potom nepsalo chybu ;)

Přidáš referenci na tu knihovnu.

ok moc díky, ještě kde seženu ten gnome ? prosím

Není potřeba, stačí to přepsat na standardní .net funkce.
