Regex + Remove all text before match

Question

I\'m trying to figure out a way to remove all text in a string before match in Regex. I\'m coding this in C#.

For example, if the string is \"hello, test matching\

Answer 1

*Updated, using matchcollection

string test = "hello, test matching";

string regexStrTest;
regexStrTest = @"test\s\w+";       
MatchCollection m1 = Regex.Matches(test, regexStrTest);
//gets the second matched value
string value = m1[1].Value;
