Question

I have a string with text inside curlies like this:

{field1}-{field}+{field3}Anthing{field4}  

from which I need to get an array like this:

['field1', 'field2', 'field3', 'field4']

Is there a way to do it using regexes in c#?

Answer 1

You can use Split and Linq:

string[] words = s.Split('+')
                  .Select(word => word.Substring(1, word.Length - 2))
                  .ToArray();

Or, you can match for {...} tokens using a simple regular expression:

MatchCollection matches = Regex.Matches(s, @"\{(\w*)\}");
string[] words = matches.Cast<Match>()
                        .Select(m => m.Groups[1].Value)
                        .ToArray();

\w* would only match alphanumeric characters, you may want to replace it with [^}]* or .*?.
