It is assumed that you want to call your programme like this: e.g.

C#

calling John

Then you must parse the arguments.

C#

using System;

namespace calling
{
    class Program
    {
        static int Main(string[] args)
        {
            if (args.Length == 0)
            {
                Console.WriteLine("Please enter a name.");

                Console.ReadKey();

                return 1;
            }

            Console.WriteLine($"Hello {args[0]}");

            Console.ReadKey();

            return 0;
        }
    }
}

"John" is the first argument thus its index will be 0.

C#

Console.ReadKey();

prevents the application from exiting without you seeing anything.
