regex - C# Regular expression pattern what this matches for -

can sombody explain regex check for

regex x = new regex("{([^}]+)}"); 

it looks {...} (1 or more) non-} inside. if successful puts content of {...} in capture group 1.

regex x = new regex("{([^}]+)}"); var m = x.match("{hello}");  string str0 = m.groups[0].tostring(); // {hello} string str1 = m.groups[1].tostring(); // hello 

group 0 whole match.

var m2 = x.match("{}"); var success = m2.success; // false 

it isn't anchored, have more 1 match each string...

var m2 = x.matches("{hello}{}{world}"); int c = m2.count; // 2 matches. {} wasn't match, {hello} , {world} 

as sidenote, if think beginning c# parser, on wrong road :-) expressions { { string str = "hello"; } str += "x"; } confuse regex, expressions { string str = "}" }. stackless regex. no fancy tricks.
