asp.net - how to split the string in c# -

I want to split the string "about {pro} problem {statement}"

< P> I want to get the output

  this {pro} of {problem}  

you can try:

  ([^ {] + | {[^}] *})  

It matches each group of characters that are either defined:

• The sequence of characters (at least one), of which none {; Or
• a { character, which is not } than any number of characters, then all }
