Split string by two characters in c#

Question

Him I would like to split string by two characters.

For example I have string like this one: "xx-aa-[aa]-22-[bb]". I want to retrieve string array of [aa] and [bb]. All characters between [ ].

First I can split by '-', so I'll have string array

var tmp = myString.Split('-');

But now how can I retrieve only strings between [] ?

You can use following regex:

\[(.+?)\]

Use global flag to match all the groups.
