C# in a Nutshell, Second Edition

Name

Capture

Synopsis

This class represents a single result from a capturing group, which is a segment of a regular expression that is delineated, usually by parentheses. The parentheses signal .NET’s regular expression engine to save that segment’s result for later use. Capture objects compose the collection returned by Group.Captures. The Value property gets the captured substring. The Index property contains the starting position of the capture in the input string, while Length contains the length of the captured string.

public class Capture {
// Public Instance Properties
   public int Index{get; }
   public int Length{get; }
   public string Value{get; }
 // Public Instance Methods
   public override string ToString( );
