示例1: Test
' 导入命名空间
Imports System.Text.RegularExpressions
Public Module Test
Public Sub Main()
' Define a case-insensitive regular expression for repeated words.
Dim rxInsensitive As New Regex("\b(?<word>\w+)\s+(\k<word>)\b", _
RegexOptions.Compiled Or RegexOptions.IgnoreCase)
' Define a case-sensitive regular expression for repeated words.
Dim rxSensitive As New Regex("\b(?<word>\w+)\s+(\k<word>)\b", _
RegexOptions.Compiled)
' Define a test string.
Dim text As String = "The the quick brown fox fox jumps over the lazy dog dog."
' Find matches using case-insensitive regular expression.
Dim matches As MatchCollection = rxInsensitive.Matches(text)
' Report the number of matches found.
Console.WriteLine("{0} matches found in:", matches.Count)
Console.WriteLine(" {0}", text)
' Report on each match.
For Each match As Match In matches
Dim groups As GroupCollection = match.Groups
Console.WriteLine("'{0}' repeated at positions {1} and {2}", _
groups.Item("word").Value, _
groups.Item(0).Index, _
groups.Item(1).Index)
Next
Console.WriteLine()
' Find matches using case-sensitive regular expression.
matches = rxSensitive.Matches(text)
' Report the number of matches found.

' Report on each match.
For Each match As Match In matches
Dim groups As GroupCollection = match.Groups

' 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
