using System;

namespace HelloWorld

{

  public class Program

  {

    // This is where the program starts.

    static void Main(string[] args)

    {

      // Prompt user to enter a name.

      Console.WriteLine(“Enter your name, please:”);

      // Now read the name entered.

      string name = Console.ReadLine();

      // Greet the user with the entered name.

      Console.WriteLine(“Hello, “ + name);

      // Wait for user to acknowledge the results.

      Console.WriteLine(“Press Enter to terminate . . . “);

      Console.Read();

    }

  }

}
