c# - Match text surrounded by "{{" and "}}"

I'm looking for a Regex which can do this : My text :

"Blablabla {{ blabla1 }} blablablabla {{ blablabla2 {{ blabla3 }} }} blablabla"

What I want to extract :

"blabla1" and "blablabla2 {{ blabla3 }}"

Does anyone has an idea ?

I tried with : "{{(.)*}}" but it returns "blabla1" and "blabla3"

You can use balancing groups for counting and matching nested constructs like these. For example:

(?x) {{ ( (?: [^{}]+ | (?<open>{{) | (?<-open>}}) )* (?(open)(?!)) ) }}
