int values = 0;
int sum = 0;

while (true)
{
  Console.WriteLine("Provide a value, a negative value ends the program");
  int value = Convert.ToInt32(Console.ReadLine());
  if (value < 0)
  {
    break;
  }

  values = values + 1;
  sum = sum + value;
}

if (sum == 0)
{
  Console.WriteLine("The average of the values could not be calculated.");
}
else
{
  Console.WriteLine("Average of values: " + (1.0 * sum / value));
}

You will find following structure in the exercise:

using System;

namespace exercise_05
{
  class Program
  {
    public static void Main(string[] args)
      {
       string name = "Ada Lovelace";
       // Write your code here:
       }
  }
}

This is not a coding exorcist.
