using System; 
 
class MainClass { 
  public static void Main() { 
    int[] nums = new int[4]; 
 
    Console.WriteLine("Before exception is generated."); 
 
    // Generate an index out-of-bounds exception. 
    for(int i=0; i < 10; i++) { 
      nums[i] = i; 
      Console.WriteLine("nums[{0}]: {1}", i, nums[i]); 
    } 
 
  } 
}

Before exception is generated.
nums[0]: 0
nums[1]: 1
nums[2]: 2
nums[3]: 3

Unhandled Exception: System.IndexOutOfRangeException: Index was outside the bounds of the array.
