Regex
Synopsis
This class represents a regular
expression. Use
it to search for patterns in string data. It provides static methods
that search for a pattern without explicitly creating
Regex instances as well as instance methods that
allow you to interact with a Regex object.
The various static methods employed by Regex take
the input string to search for as the first argument and the regular
expression pattern string as the second. This is equivalent to
constructing a Regex instance with a pattern
string, using it, and destroying it immediately. Most methods are
overloaded as instance methods as well. These do not require a
pattern argument, as this is provided with the constructor.
The Match( ) and Matches( )
methods search an input string for a single match or all matches.
Their overloads are the same. The first argument is the input string.
You can specify which position in the string the search should start
at using a second integer parameter. Match( ) also
lets you specify the length of substring to search after that
position. IsMatch( ) works the same way as
Match( ), except that it returns a boolean
indicating whether the string contains a match.
The Split( ) method acts like the
System.String.Split( ) method. It uses the
Regex pattern as a delimiter to split the input string into an array of substrings. (The delimiter is not included in the substrings.) You can provide a maximum number of substrings to return, in which case the last substring returned is the remainder ...
