StreamReader my_stream_reader = new StreamReader(@"E:\test.txt");
            string getligne = my_stream_reader.ReadToEnd().ToString();
            if (getligne.Contains(" "))
            {
                getligne = getligne.Replace(" ", " ");
            }
            string[] sArray = getligne.Split(' ');

            foreach (string s in sArray)
                Console.WriteLine(s);

探讨

情况不妙，改进代码后为：
  StreamReader my_stream_reader = new StreamReader("results.txt");
  string getligne = my_stream_reader.ReadLine().ToString();
  if (getligne.Contains(" "))
  {
  getligne = getligne……


------解决方案--------------------
List<string> lst=new List<string>(File.ReadAllLines(""))
foreach(string s in lst)
{
string[] arr= s.Split(new string[]{" ","\r\n"},StringSplitOptions.RemoveEmptyEntries);
}
