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

Solution 1

Use a regex:

C#

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);

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

1) Add the regex declaration to your class.
2) Execute the regex.Matches line when you want to find the lines.
3) You then have the two lines you are looking for extracted into "ms". Since it implements ICollection you can treat it as a normal List - access elements by number, using a foreach, whatever you need to do with them...
If you aren't sure about something, Google will help, and you could learn something useful!
