Hi,

I need to read a file like this:

#: hello.hello_world
msgid "Hello, world!"
msgstr "Bonjour, le monde !"

#: hello.running_as
#, object-pascal-format
msgid "This program is running as process number %d."
msgstr "Ce programme est exécuté en tant que processus numéro %d."

and get a sortedlist with all msgid as keyz and msgstr as values.
"Hello, world!" = "Bonjour, le monde !"
"This program is running as process number %d." = "Ce programme est
exécuté en tant que processus numéro %d."

What's the best solution to do this please ?

Read all strings "one by one" ?

Jean-Luc !

Yes, I'd read a line at a time and process lines I'm interested in.
I'd personally create a class to encapsulate the key and the value,
but you could also reuse the generic KeyValuePair struct.

When you say you want a *sorted* list, what do you want it sorted by?
If it's just "where the entries came" then you just need a List which
you add to at the end each time.

But how to use a List<> to get key / value elements ?
After, I need to get value efficiently with (for example)
MyList["mykey"]

Ah - you didn't say that. In that case use a List for the "in order"
version and a Dictionary for key lookups.

Finally, I use a Dictionnary. Thanks for your help
