Check the sample program below. It reads your file line by line, then splits it into individual words (split on space) and then takes the last word and adds it into a list. You can convert this list into an int Array if you want.

C#

class Program
{
    static void Main(string[] args)
    {
        List<int> listOfNumbers = new List<int>();
        using (StreamReader sr = new StreamReader(@"C:\Test.txt"))
        {
            while (!sr.EndOfStream)
            {
                string line = sr.ReadLine();
                if (!string.IsNullOrEmpty(line))
                {
                    listOfNumbers.Add(Convert.ToInt32(line.Split(' ').Last()));
                }
            }
        }
    }
}

C#

//You can do this  in two  lines  of code
//if you just want the substring after the last space

 string[] lines = File.ReadAllLines(@"C:\Test.txt");

   List<string> OutputLines = (from line in lines
                let index = line.LastIndexOf(' ')
                where index > -1 && index < line.Length - 2
                select line.Substring(index + 1)).ToList();

//Or, in fluent syntax

   List<string> OutputLines  =
                lines.Select((line) => new { text=line, index = line.LastIndexOf(' ') })
                    .Where(x => x.index > -1 && x.index < x.text.Length - 2)
                    .Select(x => x.text.Substring(x.index + 1))
                    .ToList();

//or, with a foreach loop

 List<string> OutputLines = new List<string>();
foreach (var line in lines)
            {
                int index = line.LastIndexOf(' ');
                if (index > -1 && index < line.Length - 2) 
                OutputLines.Add(line.Substring(index + 1));
                
            }
