' 導入命名空間
Imports System.Text.RegularExpressions
Module Example
Public Sub Main()
Dim text As String = "One car red car blue car"
Dim pattern As String = "(\w+)\s+(car)"
' Instantiate the regular expression object.
Dim r As Regex = new Regex(pattern, RegexOptions.IgnoreCase)
' Match the regular expression pattern against a text string.
Dim m As Match = r.Match(text)
Dim matchcount as Integer = 0
Do While m.Success
matchCount += 1
Console.WriteLine("Match" & (matchCount))
Dim i As Integer
For i = 1 to 2
Dim g as Group = m.Groups(i)
Console.WriteLine("Group" & i & "='" & g.ToString() & "'")
Dim cc As CaptureCollection = g.Captures
Dim j As Integer
For j = 0 to cc.Count - 1
Dim c As Capture = cc(j)
Console.WriteLine("Capture" & j & "='" & c.ToString() _
& "', Position=" & c.Index)
Next
Next
m = m.NextMatch()
Loop
End Sub
End Module輸出：
Match1 Group1='One' Capture0='One', Position=0 Group2='car' Capture0='car', Position=4 Match2 Group1='red' Capture0='red', Position=8 Group2='car' Capture0='car', Position=12 Match3 Group1='blue' Capture0='blue', Position=16 Group2='car' Capture0='car', Position=21
