namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.Write("How many entries?");
            int entries;
            if(!int.TryParse(Console.ReadLine(), out entries))
            {
                Console.WriteLine("You must enter a valid number");
                Environment.Exit(0);
            }
            Dictionary<string, string> phonebook = new Dictionary<string, string>();
            for(int i = 0; i < entries; i++)
            {
                Console.Clear();
                Console.Write("Enter name:");
                string name = Console.ReadLine();
                Console.Write("Enter phone number:");
                string number = Console.ReadLine();
                phonebook.Add(name, number);
            }
            // do something with your dictionary object
        }
    }
