如何从文本(字符串)中提取字符串? [英] How to Pull String from Text(String) ?

问题描述

朋友，

我想从C#语言的字符串中拉出字符串，例如:

Hi Friends,

I want to Pull string from string in C# language, exemple :

RemoteNode     = 0
Rem Node Name  = ISP-0(ISP)
Encapsulation  = PPPoE
Multiplexing   = LLC-based
Channel active = Yes
VPI/VCI value  = 0/38
IP Routing mode= Yes
Bridge mode    = No
PPP Username   = ********
	
PPP Password   = ********
PPP Username_ext2   = 
PPP Password_ext2   = 
Service name   = 
Remote IP Addr        = 0.0.0.0
Remote IP Subnet Mask = 0.0.0.0

此文本正在更改，我想拉这个字符串

如何从字符串中得到这两行:

This text is changing and I want to pull this string

How to get this two lines :

PPP Username   = ********
	
PPP Password   = ********

?

谢谢您，

from the string ?

Thank you,

推荐答案

使用正则表达式:

Use a regex:

public static Regex regex = new Regex(@"PPP\sPassword\s+.*|PPP\sUsername\s+=.*",
    RegexOptions.CultureInvariant
    | RegexOptions.Compiled
    );

//// Capture all Matches in the InputText
MatchCollection ms = regex.Matches(InputText);

获取 Expresso [ ^ ]-它是免费的，它可以检查并生成正则表达式.

Get a copy of Expresso [^] - it''s free, and it examines and generates Regular expressions.
