Regular expression tips (constantly updated ...)

We use regular expressions most of the time to do input validation, that is, to match only one qualifying result, but if we parse some special format of the text, we need multiple matching results, then how to get multiple matching results? Here are two ways to do this:

Method One:

Using the Matches method, get the matchcollection result, and traverse the matchcollection to get a matching result.

string equ = @ "\w*@.*"new Regex (@ "\d+?\d+_?\d*"in//  using Matches method  {    Console.WriteLine (m.value);}

Method Two:

Using the NextMatch method, when the match succeeds, continue to match down.

// You can also use the match method to match the first  while (m.success) {    Console.WriteLine (m.value);     // use NextMatch to get the next }
