Learn
At the very beginning of your C# journey, you learned about Console.WriteLine()
. You used this tool with nearly every type, from int
and bool
to Dissertation
and Diary
:
bool b = true; Diary d = new Diary(); Console.WriteLine(b); Console.WriteLine(d);
We can use this same tool with every type because every type inherits from Object
!
Under the hood, Console.WriteLine()
uses ToString()
, which is defined in Object
. Every object needs some kind of string
representation to be printed in text. These two lines are equivalent:
Console.WriteLine(b); Console.WriteLine(b.ToString());
Instructions
1.
Let’s prove to ourselves that ToString()
is used when printing to the console.
First, override the ToString()
method in the Diary
class. Have the method return the string "Surprise!"
.
2.
Back in Program.cs, construct a Diary
object and pass it directly to Console.WriteLine()
.
You should see your surprise printed!
