C# - remove part of listbox items -

i have listbox has collection of files directory , need remove extension them. m4a format should make bit easier. have searched , cannot find solution.

i new programming , appreciate help. if request example appreciate , please use lstsong instead of placeholder because confused whats placeholder , not in examples.

as requested code writes it:

string[] songspaths = system.io.directory.getfiles(librarypath + "/" + albumpath + "/" + songpath);  list<string> listsongs = new list<string>();  foreach (var f in songspaths) {    string songs = f.split('\\').last();    lstsong.items.add(songs); } 

i unsure how code works. understand of written friend me. why going afterwards. again.

understanding comment need filename of files, without path or extension. can use path.getfilenamewithoutextension

string[] songspaths = system.io.directory.getfiles(librarypath + "/" + albumpath + "/" + songpath); // files specified directory  list<string> listsongs = new list<string>();  foreach (var f in songspaths) {    lstsong.items.add(path.getfilenamewithoutextension(f)); // store filename without path or extension in list } 

and explain code friend has wrote:

string songs = f.split('\\').last(); 

the string.split method diviedes string array of substrings delimited given character. in case it's (escaped) backslash. .last() returns last element of array.
