使用例

 
Dim text As String = "One car red car blue car"
Dim pat As String = "(\w+)\s+(car)"
' Compile the regular expression.
Dim r As Regex = new Regex(pat, RegexOptions.IgnoreCase)
' Match the regular expression pattern against a text string.
Dim m As Match = r.Match(text)
Dim matchcount as Integer = 0
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 j
   Next i
   m = m.NextMatch()
End While
