Question

Hi guys I wrote this code and i have two errors.

1. Invalid rank specifier: expected ‘,’ or ‘]’
2. Cannot apply indexing with [] to an expression of type ‘int’

Can you help please?

    static void Main(string[] args)     {         ArrayList numbers = new ArrayList();          foreach (int number in new int[12] {10,9,8,7,6,5,4,3,2,1}) //error No.1         {             numbers.Add(number);         }          numbers.Insert(numbers.Count - 1, 75);         numbers.Remove(7);         numbers.RemoveAt(6);          for(int i=0; i<numbers.Count; i++)         {             int number = (int) number[i]; // error No.2             Console.WriteLine(number);         }     }

using System; using System.Collections;  namespace ConsoleApplication3 {     class Program     {         static void Main(string[] args)         {             ArrayList numbers = new ArrayList();             foreach (int number in new int[] { 10, 9, 8, 7, 6, 5, 4, 3, 2, 1 })             {                 numbers.Add(number);             }             numbers.Insert(numbers.Count - 1, 75);             numbers.Remove(7);             numbers.RemoveAt(6);             for (int i = 0; i < numbers.Count; i++)             {                 int number = (int)numbers[i];                 Console.WriteLine(number);             }         }     } }
