This section provides a tutorial example on how to use 'switch' statements to print business hours based on today's date.

The following program shows how a "switch" statement is used to print a specific message depending on which day of week it is today:

// Switches.cs

class Switches {
   public static void Main() {
      int today;
      string message;

      today = (int) System.DateTime.Today.DayOfWeek;
      switch (today) {
         case 1:
            message = "Today is Monday. We are open until 5 p.m.";
            break;
         case 2:
            message = "Today is Tuesday. We are open until 5 p.m.";
            break;
         case 3:
            message = "Today is Wednesday. We are open until 5 p.m.";
            break;
         case 4:
            message = "Today is Thursday. We are open until 7 p.m.";
            break;
         case 5:
            message = "Today is Friday. We are open until 7 p.m.";
            break;
         default:
            message = "Sorry, we are closed on weekends.";
            break;
      }
      System.Console.WriteLine(message);
   }
}

Output:

Sorry, we are closed on weekends.

Note that we are using the DateTime structure provided by the C# compiler to get the day of week of today, casted to the "int" type. By checking the reference manual, we can see that the day of week has a value of 0 to 6, representing Sunday to Saturday, respectively. Of course, the above output was generated on a Sunday.
