Reading Lines from a file

Here is my code so far:

private void btnFile_Click(object sender, System.EventArgs e)
{
      string scores = "";
      string dir = @"C:\C#.NET\Files\";
      if(!Directory.Exists(dir))
      Directory.CreateDirectory(dir);

      string path = dir + "studentlist.txt";
      StreamReader textIn = new StreamReader(new FileStream(path, FileMode.Open, FileAccess.Read));

      ArrayList dummies = new ArrayList();
      while(textIn.Peek() != -1)
      {
            string row = textIn.ReadLine();
            string[] columns = row.Split('|');
                  
            int x = 1;

               
--->            while(columns[x] != null)
            {
                  scores += columns[x].ToString();
                  x++;
            }

            Student student = new Student(columns[0], columns[1]);
      //      student.Name = columns[0];
      //      student.Scores = columns[1];
            dummies.Add(student);
      }

                  foreach(object s in dummies)
      {
            mainList.Items.Add(s.ToString());
      }
      textIn.Close();

}

I want the parser to read the line, which is in the format of "Someone's Name|54|65|76|76". So for column[0] we have the name, and columns[1] and higher (number can vary), we have the scores. In the line of code indicated, how do I make the parser read through all the columns in the line after the 0th column? I can't quite get it working.

I can only get the listbox to display "Someones Name|44", but I need to display all the numbers after that too.

thanks.
