推荐答案

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()));
                }
            }
        }
    }
}

//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));
                
            }
