.net 3.5 - Strange behavior of the '??'-operator in C# 3.5 -

is bug or interpreting '??'-operator wrong? check out property below , comments.

i'm using c# .net 3.5

private list<mytype> _mytypelist; private list<mytype> mytypelist { { //the 2 code lines below should each behave 3 under, don't? //the ones uncommented working, commented result in list returning empty (newly created suppose). //return _mytypelist ?? new list<mytype>(); //return _mytypelist == null ? new list<mytype>() : _mytypelist; if (_mytypelist == null) _mytypelist = new list<mytype>(); homecoming _mytypelist; } }

edit: sorry looked @ question when freshly asked, there errors in got confuse everyone.

thanks great , fast feedback! i've understood error made. thanks!

this line:

return _mytypelist == null ? new list<mytype>() : _mytypelist;

is equivalent to:

if (_mytypelist == null) homecoming new list<mytype>(); homecoming _mytypelist;

not to:

if (_mytypelist == null) _mytypelist = new list<mytype>(); homecoming _mytypelist;

the version ??, added later, unreadable won't analyze it. let's ? right first.

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...
