How to search for numbers in txt file C# ?

[Neptuno67]

I open a .txt file and read numbers separated by enters or spaces into an array list.

Now what I want to do is to search (for 1 2 9 ) and send to the console.
I have tried a lot of code but nothing seems to work :(

This is my current code :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;
namespace Padroes
{
class Program
{
    static void Main(string[] args)
    {
        try
        {
 
 
            // Open the text file using a stream reader.
            const string FILENAME = @"Example.txt";
 
 
                List<List<int>> data = new List<List<int>>();
 
                string inputLine = "";
                StreamReader reader = new StreamReader(FILENAME);
 
                while ((inputLine = reader.ReadLine()) != null)
                {
                    inputLine = inputLine.Trim();
                    if (inputLine.Length > 0)
                    {
                        List<int> inputArray = inputLine.Split(new char[] { ' ' }, StringSplitOptions.RemoveEmptyEntries).Select(x => int.Parse(x)).ToList();
 
                        data.Add(inputArray);
                    Console.WriteLine(inputLine);
                    }
                }
            }
 
        catch (Exception e)
        {
            Console.WriteLine("The file could not be read:");
            Console.WriteLine(e.Message);
        }
 
        Console.ReadKey();
    }
}
}

Whith this code this is my output:

Now what can I do to search only for ( 1 2 9 ) and send only the (1 2 9) to console ?

if (inputline.Trim() == "1 2 9")
{
    // do something
}
