Writing and calling methods


Methods are type members that execute a block of statements.

A method that performs some actions but does not return a value shows this by showing that it returns the void type before the name of the method. A method that performs some actions and returns a value shows this by showing that it returns the type of that value before the name of the method.

For example, you will create two methods:

  • WriteToConsole: This will perform an action (writing a line), but it will return nothing from the method, indicated by the void keyword

  • GetOrigin: This will return a string value, indicated by the string keyword

Inside the Person class, statically import System.Console, and then add the following code:

    // methods 
    public void WriteToConsole() 
    { 
      WriteLine($"{Name} was born on {DateOfBirth:dddd, d MMMM
      yyyy}"); 
    } 
 
    public string GetOrigin() 
    { 
      return $"{Name} was born on {HomePlanet}"...
