Dictionaries with timespans and messages

Question

Hello

I try to use dictionaries 

And I would like to know how could I in dictionary use a specific time range to display the appropriate message.

 

For example 

If it's lunchtime, then one message.

If it is morning now, time is something else.

 

My attempt here

 

namespace ConsoleApp1
{

    class Program
    {
        static string Method()

        {
            Console.WriteLine("The Timespan is : {0}", variable);
        }
        static void Main(string[] args)
        {
            var greetings = new List<object>() {"Good morning", "Good day", "Good evenining"};
            var timePoints = new List<object>() { 9, 12, 15, 22};

            for (int i = 0; i < greetings.Count; i++)
            {
                //System.Console.WriteLine(i + 1 + " Pair:" + "\n" + "C# type inside IL is: " + greetings[i].GetType() + "\n" + timePoints[i].GetType() + "\n");
            }
        }
    }
}
