示例1: Main
//引入命名空间
using System;
using System.Text.RegularExpressions;
public class Test
{
public static void Main ()
{
// Define a case-insensitive regular expression for repeated words.
Regex rxInsensitive = new Regex(@"\b(?<word>\w+)\s+(\k<word>)\b",
RegexOptions.Compiled | RegexOptions.IgnoreCase);
// Define a case-sensitive regular expression for repeated words.
Regex rxSensitive = new Regex(@"\b(?<word>\w+)\s+(\k<word>)\b",
RegexOptions.Compiled);
// Define a test string.
string text = "The the quick brown fox fox jumps over the lazy dog dog.";
// Find matches using case-insensitive regular expression.
MatchCollection matches = rxInsensitive.Matches(text);
// Report the number of matches found.
Console.WriteLine("{0} matches found in:\n {1}",
matches.Count,
text);
// Report on each match.
foreach (Match match in matches)
{
GroupCollection groups = match.Groups;
Console.WriteLine("'{0}' repeated at positions {1} and {2}",
groups["word"].Value,
groups[0].Index,
groups[1].Index);
}
Console.WriteLine();
// Find matches using case-sensitive regular expression.
matches = rxSensitive.Matches(text);
// Report the number of matches found.
Console.WriteLine("{0} matches found in:\n {1}",
matches.Count,
text);
// Report on each match.
foreach (Match match in matches)
{
GroupCollection groups = match.Groups;
Console.WriteLine("'{0}' repeated at positions {1} and {2}",
groups["word"].Value,
groups[0].Index,
groups[1].Index);
}
}
}
// The example produces the following output to the console:
// 3 matches found in:
// The the quick brown fox fox jumps over the lazy dog dog.
// 'The' repeated at positions 0 and 4
// 'fox' repeated at positions 20 and 25
// 'dog' repeated at positions 50 and 54
//
// 2 matches found in:
// The the quick brown fox fox jumps over the lazy dog dog.
// 'fox' repeated at positions 20 and 25
// 'dog' repeated at positions 50 and 54
