Hinweise
Das Objekt ist unveränderlich und besitzt keinen öffentlichen Konstruktor. Instanzen werden durch die Auflistung zurückgegeben, die von Captures zurückgegeben wird. Die Match-Klasse und die Group-Klasse erweitern Capture.
Beispiel
Dim text As String = "One fish two fish red fish blue fish"
Dim pat As String = "(?<1>\w+)\s+(?<2>fish)\s*"
' Compile the regular expression.
Dim r As New Regex(pat, RegexOptions.IgnoreCase)
' Match the regular expression pattern against a text string.
Dim m As Match = r.Match(text)
While m.Success
' Display the first match and its capture set.
System.Console.WriteLine("Match=[" + m.ToString() + "]")
Dim cc As CaptureCollection = m.Captures
Dim c As Capture
For Each c In cc
System.Console.WriteLine("Capture=[" + c.ToString() + "]")
Next c
' Display Group1 and its capture set.
Dim g1 As Group = m.Groups(1)
System.Console.WriteLine("Group1=[" + g1.ToString() + "]")
