如何在两个字符串之间使用字符串 [英] How Can I take String Between Two Strings

问题描述

您好，

我正在使用VB.Net 2010，我想在两个字符串之间取字符串。

my string =ÿÿÿÿÿÿÿÿ^ 2hold up .._ AFC

我怎么能把这个^ 2持有......（长度永远不变。）

Hello,
I''m using VB.Net 2010 and i want take string between two strings.
my string = "ÿÿÿÿÿÿÿÿ^2hold up.._AFC"
How Can I take this "^2hold up.."(Lenght is never same.)

推荐答案

你听说过吗？ RegEx [ ^ ]？



如果您想找到 2持有，请使用它：

Have you ever heard about RegEx[^]?

If you would like to find 2hold up, please use it:

Imports System.Text.RegularExpressions

Module Module1

    Sub Main()
        Dim sText As String = "ÿÿÿÿÿÿÿÿ^2hold up.._AFC"
        Dim sPattern As String = "\b*(\^2hold up..)*\b"
        Dim rx As Regex = New Regex(sPattern, RegexOptions.Singleline)

        For Each m As Match In rx.Matches(sText)
            Console.WriteLine(m.Value)
        Next

        Console.ReadKey()
    End Sub

End Module

如果没有，请告诉我，我会尽力找到你正确的模式。

If not, please, let me know and i''ll try to find you proper pattern.

Dim s As String
      s = "ÿÿÿÿÿÿÿÿ^2hold up.._AFC"
      Dim start = s.IndexOf("ÿÿÿÿÿÿÿÿ") + Len("ÿÿÿÿÿÿÿÿ")
      Dim limit = s.IndexOf("_AFC") - start
      s = s.Substring(start, limit)
