I have this format of string: 110001101 and I would like to split that string to string[] by grouped chunks of 1s or 0s.
So from that string I would get splitted string[] = { "11", "000", "11", "0", "1" };
Is it possible to achieve that with Regex, I don't know where to start? Or should I find another solution...
You can use a capturing mechanism and use Regex.Split with a mere (0+) regex like this:
var txt5 = "110001101";
var res5 = Regex.Split(txt5, @"(0+)").Where(p => !string.IsNullOrEmpty(p)).ToArray();
Result:
This will work as you do not have symbols other than 0 or 1 in your input string, and the captured text is also output as array elements. The LINQ code helps eliminate any unwelcome empty elements from the resulting array (as is the case with 0s only).
So you want either consecutive zeros (0+) or consecutive ones (1+). Just iterate over the matches:
0+|1+
