尝试使用C＃REGEX匹配文件中的文件名

Question

Im trying to extract MP3 filenames from binary file. Im trying to get this regular expression to match all mp3 AND WAVE files.. Here is what I have so far..

System.Text.RegularExpressions.MatchCollection  m = System.Text.RegularExpressions.Regex.Matches(rosText, @"(\w:\\(?:\w+(?:\s+\w+)*\\)*[-_\w\s\d.\(\)\'\[\]]*\.mp3)",System.Text.RegularExpressions.RegexOptions.IgnoreCase);

MATCHES C:\\mp3\\Miami House\\New Adds 49\\Jungle_EP_(Life_In_The_Jungle_'Original_Mix')-SL-51-1(320k).mp3

DOES NOT MATCH C:\\mp3\\Miami House\\New Adds 49\\Each_&_Every_Day_Pt. 2 (Raw_Artistic_Soul_Vocal_Mix)-AR002-1(320k).mp3

C:\\mp3\\Miami House\\New Adds C:\\mp3\\Miami House\\New Adds 49\\Jungle_EP_(Life_In_The_Jungle_'Original_Mix')-SL-51-1(320k).wav

A very simple regex to match such files is:

string regex = @".*\.(mp3|wav)"

If you are however able to extract the files (in this case in the /tmp directory) into a directory you can use:

foreach (var file in Directory.EnumerateFiles ("/tmp", "*.mp3")) {
    try {
        //do something
    } catch {
        ; // optionally report error
    }
}
foreach (var file in Directory.EnumerateFiles ("/tmp", "*.wav")) {
    try {
        //do something
    } catch {
        ; // optionally report error
    }
}

as well.
