Split string into groups by inside and outside of brackets – including the brackets

I’m looking for the simplest way to parse a string into groups – including the delimiters. What’s inside and outside the { } could be anything – except for { and }.

Using this

var s = "test {#}, {1} more text {a|b|c}";  
var regEx = new Regex(@"{(.*?)}");  
var mat = regEx.Matches(s);

I get groups that are ["{#}", "{1}", "{a|b|c}"].

My desired result is ["test ", "{#}", ", ", "{1}", " more text ", "{a|b|c}"].

>Solution :

If inside and outside can be anything except for { and }:

\{[^{}]*}|[^{}]+

Explanation

• { Match the opening {
• [^{}]* Optionally match any char except { and }
• } Match the closing }
• | Or
• [^{}]+ match 1+ chars other than { and }

Regex demo

Example

string pattern = @"{[^{}]*}|[^{}]+";
string input = @"test {#}, {1} more text {a|b|c}";
foreach (Match m in Regex.Matches(input, pattern))
{
    Console.WriteLine("'{0}'", m.Value);
}

Output

'test '
'{#}'
', '
'{1}'
' more text '
'{a|b|c}'
