validate several numeric user inputs C# Console

Question

Okay, so I made this program for a small school project. It's just small Console Application were the user is supposed to enter 10 numbers and get the average result, the highest and lowest number. But I want to correct the user if he/she types in something that is not numeric. This is my code:

class Program
{
    static void Main(string[] args)
    {
        int num1, num2, num3, num4, num5, num6, num7, num8, num9, num10;

            Console.Write("Enter the 1st number: ");
            num1 = Convert.ToInt32(Console.ReadLine());

            Console.Write("Enter the 2nd number: ");
            num2 = Convert.ToInt32(Console.ReadLine());

            Console.Write("Enter the 3rd number: ");
            num3 = Convert.ToInt32(Console.ReadLine());

            Console.Write("Enter the 4th number: ");
            num4 = Convert.ToInt32(Console.ReadLine());

            Console.Write("Enter the 5th number: ");
            num5 = Convert.ToInt32(Console.ReadLine());

            Console.Write("Enter the 6th number: ");
            num6 = Convert.ToInt32(Console.ReadLine());

            Console.Write("Enter the 7th number: ");
            num7 = Convert.ToInt32(Console.ReadLine());

            Console.Write("Enter the 8th number: ");
            num8 = Convert.ToInt32(Console.ReadLine());

            Console.Write("Enter the 9th number: ");
            num9 = Convert.ToInt32(Console.ReadLine());

            Console.Write("Enter the 10th number: ");
            num10 = Convert.ToInt32(Console.ReadLine());

            int[] numbers = { num1, num2, num3, num4, num5, num6, num7, num8, num9, num10 };
            int biggestNumber = numbers.Max();
            int smallestNumber = numbers.Min();
            Console.WriteLine("Your biggest number was: " + biggestNumber);
            Console.WriteLine("Your smallest number was: " + smallestNumber);

            int result = (num1 + num2 + num3 + num4 + num5 + num6 + num7 + num8 + num9 + num10) / 10;
            Console.WriteLine("The average of your numbers are: " + result);

            Console.ReadLine();
        }
    }
}

After researching online, I found this as a possible solution:

            Console.Write("Enter the 1st number: ");
            while (Int32.TryParse(Console.ReadLine(), out num1) == false)
               {
                Console.WriteLine("Type a number please.");
               }

Although this works, to do this for each of the entries (num2, num3, num4, and so on) all the way down the code. So I thought maybe it's a simpler way to this instead of copy pasting the code block for each user input.

My question is: Is there an easier / more simplified solution to validate all the user inputs (at once maybe)?

EDIT: If you can help me I would love to see how you would implement your solution in my code :)

Answer 1

I would use a foreach loop but a while loop will also work.

Here is my solution

  var myList = new List<string>() { "1", "number2", "3", "4", "5", "6", "7", "8" };
  var numbers = new List<int>();

  foreach (var str in myList)
  {
    int myInt;
    if (!int.TryParse(str, out myInt))
      Console.WriteLine(string.Format("{0} is not a number. Type a number please.", str));
    else
      // Otherwise add the number to a new list of int's
      numbers.Add(myInt);        
  }

  // display the min / max vals only if there was not an error
  int biggestNumber = numbers.Max();
  int smallestNumber = numbers.Min();
  Console.WriteLine("Your biggest number was: " + biggestNumber);
  Console.WriteLine("Your smallest number was: " + smallestNumber);

  int result = numbers.Sum() / numbers.Count();
  Console.WriteLine("The average of your numbers are: " + result);

Answer 2

You need something like that, man. Collect all values to List and work with it :

        List<int> numbers = new List<int>();
        while (numbers.Count() < 10)
        {
            Console.Write("Enter the " + (numbers.Count() + 1) + "st number: ");
            int num;
            while (Int32.TryParse(Console.ReadLine(), out num) == false)
            {
                Console.WriteLine("Type a number please.");
            }
            numbers.Add(num);
        }

        int biggestNumber = numbers.Max();
        int smallestNumber = numbers.Min();
        Console.WriteLine("Your biggest number was: " + biggestNumber);
        Console.WriteLine("Your smallest number was: " + smallestNumber);

        int result = numbers.Sum()/numbers.Count();
        Console.WriteLine("The average of your numbers are: " + result);

        Console.ReadLine();

This is an idea only, where basically you loop until the user enters a correct number ten times. When the input is correct, the number is saved in input[indexOfInput]

static void Main(string[] args)
{
    int[] input = new int[10];
    for (int i = 0; i < 10; i++)
    {
        Console.WriteLine("Write " + (i + 1) + " number");
        int temp;
        while (!int.TryParse(Console.ReadLine(), out temp)
        {
            Console.WriteLine("Write " + (i + 1) + " number");
        }
        input[i] = temp;
    }
    // at this point you have all 10 numbers written by the user
}
