Hi !
I’m still learning about C#9, and there is a lot to learn about records. And, between all this information, I Just learn a super cool feature related to records: deconstruction.
Let’s start with a simple record definition for a pet. This one includes pet’s name and pet’s age:
public record Pet
{
public string Name { get; init; }
public int Age { get; init; }
public Pet(string name, int age)
=> (Name, Age) = (name, age);
}
This is fine, init only properties (cool feature!) and we can access the values as usual.
static void Main(string[] args)
{
var pet = new Pet("Goku", 2);
// get pet info, standard way
var gokuName = pet.Name;
var gokuAge = pet.Age;
}
So far, so good. However, if you like clean code, we can improve this a little using some new features in C#9. So, let’s start with much simpler record definition.
public record NewPet(string Name, int Age);
And we can access the pet properties using deconstruction (new term for me!)
// get pet info, C#9 deconstruction
var newPet = new NewPet("Goku", 2);
var (gokuName, gokuAge) = newPet;
I like this new one 👆 too ! I’ll always like features that improves readability and saves us a lot of extra code.
