Hello All,

I have a file which contains the below contains

Just noticed after I'd posted that you've asked this in the VB.NET rather than the C# section.

Here's the same code in VB.NET:

Imports System
Imports System.Collections.Generic
Imports System.IO
Imports System.Text
Imports System.Text.RegularExpressions

Module Program

Sub Main()

Dim lines As String() = File.ReadAllLines("sampath.txt")
Dim matches AS New List(Of String)
Dim search As String = "\abs_axle_behavior\"
Dim len As Integer = search.Length
Dim regExp As String = "\\_?" + search.Substring(1, len - 2) + "\\"

For Each line As String in lines

If Regex.IsMatch(line, regExp) Then matches.Add(line)

Next

' print out matching lines
For Each match As String in matches

Console.WriteLine(match & VbLf)

Next

Console.ReadKey()

End Sub

End Module

Hello vulpes,

your answer is correct but the provided files are very huge files which contains more than 30,000 lines so i need to get all the lines with matches for the expression.I have done some code in vbs which i will provided .In this i am reading all lines from a file to container (readAllTestview)

search= "\abs_axle_behavior\"
lentxt= Len(search)
Set reg = New RegExp
reg.MultiLine = True
reg.Global = True
regExpBuildview ="\_?" + search + "\"

reg.Pattern =regExpBuildview
For Each m In mc
MsgBox m.Value
msgbox mc.count
Next

I implemented the expression in vbscript but this is not working.

here what i should get mc.count is total matches m.Value is the entire line.
The output should be same but expression should be implemented to entire file.

Sorry to trouble you this should work in vbscript.

Thanks & Regards

Try this:

using System;
using System.Collections.Generic;
using System.IO;
using System.Text;
using System.Text.RegularExpressions;

class Program
{
static void Main()
{
string[] lines = File.ReadAllLines("sampath.txt");
List matches = new List();
string search = @"\abs_axle_behavior\";
int len = search.Length;
string regExp = @"\\_?" + search.Substring(1, len - 2) + @"\\";

foreach(string line in lines)
{
if(Regex.IsMatch(line, regExp)) matches.Add(line);
}

// print out matching lines
foreach(string match in matches) Console.WriteLine(match + "\n");
Console.ReadKey();
}
}

The output is:
