Regex.Match Method (String, String)
Updated: July 2009
Searches the specified input string for the first occurrence of the regular expression supplied in the pattern parameter.
Assembly: System (in System.dll)
- Type: System.String
The string to search for a match.
- Type: System.String
The regular expression pattern to match.
Return ValueType: System.Text.RegularExpressions.Match
An object that contains information about the match.
The static method is equivalent to constructing a Regex object with the specified regular expression pattern and calling the instance Match(String) method. In this case, the regular expression engine caches the regular expression pattern.
The pattern parameter consists of various regular expression language elements that symbolically describe the string to match. For more information about regular expressions, see .NET Framework Regular Expressions and Regular Expression Language - Quick Reference.
You can determine whether the regular expression pattern has been found in the input string by checking the value of the returned Match object's Success property. If a match is successful, the returned Match object's Value property contains the substring from input that matches the regular expression pattern. If no match is found, its value is String.Empty.
This method returns the first substring in input that matches the regular expression pattern. You can retrieve subsequent matches by repeatedly calling the returned Match object's NextMatch method. You can also retrieve all matches in a single method call by calling the Regex.Matches(String, String) method.
