Lambda Expressions

Throughout the previous sections, you have mainly used class-level methods as targets for your delegates and events, such as the ClockTicked and ClockWakeUp methods, that were also used in Exercise 3.05:

var clock = new AlarmClock();
clock.Ticked += ClockTicked;
clock.WakeUp += ClockWakeUp;
static void ClockTicked(object sender, DateTime e)
  => Console.Write($"{e:t}...");
    
static void ClockWakeUp(object sender, EventArgs e)
{
    Console.WriteLine();
    Console.WriteLine("Wake up");
}

The ClockWakeUp and ClockTicked methods are easy to follow and step through. However, by converting them into lambda expression syntax, you can have a more succinct syntax and closer proximity to where they are in code.

Now convert the Ticked and WakeUp events to use two different lambda expressions:

clock.Ticked += (sender, e) =>
{
    Console.Write($"{e...
