What is the purpose of an automatic property?
If my getter and setter don’t perform any manipulation or checks on the data why bother making a getter/setter for them rather than just accessing the variable?

Purpose is to shorten your code as your code will lose on readability if you have many properties. Properties are necessary for defining access to fields. In lessons to come you will learn why in most cases property is set to public and why is field set to private. This is a form of encapsulation and it’s essential to object-oriented programming. I think the next lesson covers it, so hold your horses :smiley:

No I think @flujible has a point. In the automatic property there is an implicitly defined variable that is private, and we only really interact with the public property. If the property is public then what really is the difference between it and a public variable? ( If no changes or conditions are put on the property?) Since they are both public then wont they have the same kind of access rules?

The only thing i can say can make sense is -with my little experience i had discovered that- when you are trying to access a variable for what ever reason in maybe another class or something, it doesn’t show up in the suggestions or intellisense, as if to say that it doesn’t exist, or that current class has no really way of accessing explicity that variable from another class. But by providing a property, it creates a more obvious way of accessing a variable. And again you woudn’t need to create a full on property, you just need to have an automatic property declared for you.

I would appreciate it if anyone checked up on my conclusion, I really want to get the basics perfected
