示例1: Example
' 导入命名空间
Imports System.Text.RegularExpressions
Module Example
Public Sub Main()
Dim keyEntered As ConsoleKeyInfo
Dim beginComment, endComment As Char
Console.Write("Enter begin comment symbol: ")
keyEntered = Console.ReadKey()
beginComment = keyEntered.KeyChar
Console.WriteLine()
Console.Write("Enter end comment symbol: ")
keyEntered = Console.ReadKey()
endComment = keyEntered.KeyChar
Console.WriteLine()
Dim input As String = "Text [comment comment comment] more text [comment]"
Dim pattern As String = Regex.Escape(beginComment.ToString()) + "(.*?)"
Dim endPattern As String = Regex.Escape(endComment.ToString())
If endComment = "]"c OrElse endComment = "}"c Then endPattern = "\" + endPattern
pattern += endPattern
Dim matches As MatchCollection = Regex.Matches(input, pattern)
Console.WriteLine(pattern)
Dim commentNumber As Integer = 0
For Each match As Match In matches
commentNumber += 1
Console.WriteLine("{0}: {1}", commentNumber, match.Groups(1).Value)
Next
End Sub
End Module
' The example shows possible output from the example:
' Enter begin comment symbol: [
' Enter end comment symbol: ]
' \[(.*?)\]
' 1: comment comment comment
' 2: comment示例2:
Dim pattern As String = "[(.*?)]"
Dim input As String = "The animal [what kind?] was visible [by whom?] from the window."
Dim matches As MatchCollection = Regex.Matches(input, pattern)
Dim commentNumber As Integer = 0
Console.WriteLine("{0} produces the following matches:", pattern)
For Each match As Match In matches
commentNumber += 1
Console.WriteLine("{0}: {1}", commentNumber, match.Value)
Next输出：
1: ? 2: ? 3: .
示例3:
Dim pattern As String = Regex.Escape("[") + "(.*?)]"
Dim input As String = "The animal [what kind?] was visible [by whom?] from the window."
Dim matches As MatchCollection = Regex.Matches(input, pattern)
Dim commentNumber As Integer = 0
Console.WriteLine("{0} produces the following matches:", pattern)
For Each match As Match In matches
commentNumber += 1
Console.WriteLine(" {0}: {1}", commentNumber, match.Value)
Next输出：
\[(.*?)] produces the following matches: 1: [what kind?] 2: [by whom?]
