The problem


The problem: It crashes on me!!! The problem highlighted in red color, it tells me "Index was outside the bounds of the array", I know what it means, but i cant find the problem....

My Solution:


  static void Main(string[] args)
  {
  School[] schools = new School[5];
  string schoolName;
  int schoolStudentAmount;
  Console.WriteLine("Please enter information about 5 school: ");

  for (int index = 0; index < 10; index++)
  {
  Console.WriteLine("Details for each school: ", index + 1);
  Console.WriteLine(" Enter school name : ");
  schoolName = Console.ReadLine();
  Console.WriteLine("Enter amount of students in the school: ");
  schoolStudentAmount = Convert.ToInt32(Console.ReadLine());
  schools[index] = new School(schoolName,schoolStudentAmount);

  }
  Console.WriteLine("The schools and amount of students in it");
  for (int index = 0; index < 10; index++)
  Console.WriteLine(schools[index]);
  Array.Sort(schools);

  Console.WriteLine("The schools and enrolled students sorted from smallest to largest");
  for (int index = 0; index < 6; index++)
  Console.WriteLine(schools[index]);

====================
  private string schoolName;
  private int schoolStudentsAmount;

  public string SchoolName
  {
  get { return schoolName; }
  set { schoolName = value; }
  }
  public int SchoolStudentsAmount
  {
  get { return schoolStudentsAmount; }
  set { schoolStudentsAmount = value; }
  }
  public School(string schoolName, int schoolStudentsAmount)
  {
  this.schoolName = schoolName;
  this.schoolStudentsAmount = schoolStudentsAmount;
  }
  public override string ToString()
  {
  return String.Format("School name {0}, amount of students {1}.", schoolName, schoolStudentsAmount);
  }
  public int CompareTo(School other)
  {
  return this.schoolStudentsAmount.CompareTo(other.schoolStudentsAmount);
  }
