C # - Difference between automatic property and return of support field?

Question

A simple question, I think, but what is the difference between these lines of code:

Code 1

public int Temp { get; set; } 

and

Code 2

private int temp;
public int Temp { get { return temp; } }

I understand that the automatic property in accordance with code 1 will perform the same function as code 2?

I read Head First C # and it’s hard for me to understand why it uses two different ways to do the same?

Answer 1

The main difference between your Code1 and Code2 is that in # 1 the property is configurable.

You can achieve the same by using automatic properties, because the installer may be closed:

public int Temp { get; private set; }
