c# - Exclude results from Directory.GetFiles -

if want phone call directory.getfiles , have homecoming files match pattern *.bin want exclude of files match pattern log#.bin # running counter of indeterminate length. there way filter out results @ step of passing in search filter getfiles or must result array remove items want exclude?

you can utilize linq, directory.enumeratefiles() , where() filter - way end files want, rest filtered out.

something should work:

regex re = new regex(@"^log\d+.bin$"); var logfiles = directory.enumeratefiles(somepath, "*.bin") .where(f => !re.ismatch(path.getfilename(f))) .tolist();

as pointed out directory.enumeratefiles requires .net 4.0. cleaner solution (at cost of little more overhead) using directoryinfo / enumeratefiles() returns ienumerable<fileinfo> have direct access file name , extension without farther parsing.

c# .net

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
