If you need a refresher on how Regular Expressions work, check out our first!C# supports regular expressions through the classes in thenamespace in the standard.NET framework. While there are some differences in advanced featuressupported by the.NET regular expression library compared to PCRE, they both share a large partof the syntax and patterns and expressions can be used in C# and other languages.In the examples below, be sure to import the following namespaces at the top of the source fileif you are trying out the code. Using System.Text.RegularExpressions;Verbatim String LiteralsWhen writing regular expression in C#, it is recommended that you useinstead of regular strings.

Verbatim strings begin with a special prefix ( @) and signal C# notto interpret backslashes and special metacharacters in the string, allowing you to pass them throughdirectly to the regular expression engine.This means that a pattern like 'nw' will not be interpreted and can be written as @'nw'instead of 'nw' as in other languages, which is much easier to read. Matching a stringIn the System.Text.RegularExpressions namespace is a class, which encapsulates the interfaceto the regular expressions engine and allows you to perform matches and extract information from textusing regular expressions.To test whether a regular expressions matches a string, you can use the static methodwhich takes an optional set of RegexOptions enums. This returns aobject which contains information about where the match (if any) was found. // Lets try and reverse the order of the day and month in a few date// strings.
