The Matches method uses lazy evaluation to populate the returned MatchCollection object. NET Regular Expressions and Regular Expression Language - Quick Reference. For more information about regular expressions, see. The pattern parameter consists of regular expression language elements that symbolically describe the string to match. The static Matches methods are equivalent to constructing a Regex object with the specified regular expression pattern and calling the instance method Matches. It is equivalent to the following code: Match match = Regex.Match(input, pattern, options) ĭim match As Match = Regex.Match(input, pattern, options) The Matches(String, String, RegexOptions) method is similar to the Match(String, String, RegexOptions) method, except that it returns information about all the matches found in the input string, instead of a single match. The regular expression pattern \b\w+es\b is defined as shown in the following table. ' The example displays the following output: Call Matches method without specifying any options.įoreach (Match match in Regex.Matches(sentence, pattern,Ĭonsole.WriteLine("Found '", match.Value, match.Index)
String pattern = sentence = "NOTES: Any notes or comments are optional." As the output shows, the two methods return different results. In both cases, the time-out interval is set to one second. It then calls the Matches(String, String, RegexOptions, TimeSpan) method to perform a case-insensitive comparison of the pattern with the input string. The following example calls the Matches(String, String, RegexOptions, TimeSpan) method to perform a case-sensitive comparison that matches any word in a sentence that ends in "es". MatchTimeout is negative, zero, or greater than approximately 24 days. Options is not a valid bitwise combination of RegexOptions values.
