Fetching the text within "<> " in C#

Question

I am trying to fetch just the text within the double angle brackets: from a text like this , However it returns me the whole string, while i just want to fetch the text within the double <<>> brackets.

line2="Name: <<NAME>>   (<<COURSE>>)"
var pattern=@"<<.*?>>";
MatchCollection matches= Regex.Matches(line2,pattern);

Am i doing it correctly , please guide?

It gives me output in this format: <> and <>, which is not what i want i just want the NAME and COURSE. — ShrawaniSilwal, Nov 04 '17 at 00:17
You should look into [capturing groups](https://stackoverflow.com/questions/6375873/regular-expression-groups-in-c-sharp). — oowekyala, Nov 04 '17 at 01:13

Use this grouping construct: (?< name > subexpression ), like:

string line2 = "Name: <<NAME>>   (<<COURSE>>)";
var pattern = @"<<(?<value>\w+)\>>";
MatchCollection matches = Regex.Matches(line2, pattern);
string name = matches[0].Groups["value"].Value; // "NAME"
string course = matches[1].Groups["value"].Value; // "COURSE"

It puts the captured subexpression into a named group (here "value"). To access the matches use the Groups array, just like I did it above.

Further information provides the quick-reference for regular expressions.
