Answer 1

 private static int[] ConvertIntToArray(int variable)
        {
            string converter = "" + variable;
            int[] convertedArray = new int[converter.Length];
            for (int i=0; i < convertedArray.Length;i++) //it can be also converter.Length
            {
                convertedArray[i] = int.Parse(converter.Substring(i, 1));
            }
            return convertedArray;
        }

We get int via using method. Then, convert it to string immediately (123456->"123456"). We have a string called converter and carry to int value. Our string have a string.Length, especially same length of int so, we create an array called convertedArray that we have the length, that is converter(string) length. Then, we get in the loop where we are convert the string to int one by one via using string.Substring(i,1), and assign the value convertedArray[i]. Then, return the convertedArray.At the main or any method you can easily call the method.

Answer 2

Integer or Long to Integer Array C# Convert it to char array and subtract 48.

 public static int[] IntToArray(int value, int length)
    {
        char[] charArray = new char[length];
        charArray = value.ToString().ToCharArray();
        int[] intArray = new int[length];
        for (int i = 0; i < intArray.Length; i++)
        {
            intArray[i] = charArray[i] - 48;
        }

        return intArray;
    }

    public static int[] LongToIntArray(long value, int length)
    {
        char[] charArray = new char[length];
        charArray = value.ToString().ToCharArray();
        int[] intArray = new int[length];
        for (int i = 0; i < intArray.Length; i++)
        {
            intArray[i] = charArray[i] - 48;
        }

        return intArray;
    }
