I'm using C # and I got the following doubt,

In a class in which I define a calculated read-only property, for example, a simple class

public class UnaClase
{
    public int Num1 { get; set; }
    public int Num2 { get; set; }
    public int Suma
    {
        get
        {
        return Num1 + Num2;
        }
    }

    public UnaClase(int num1,int num2)
    {
        Num1 = num1; Num2 = num2;
    }
}

At what moment in the life cycle of an instance of UnaClase will the calculation Num1+Num2 be made?

When creating the instance or each time I use the property?

c# clase

Properties can also be defined as public "access points" to private data, either to obtain their value get , or to assign them value set . It is correct how much they already told you, they are evaluated at the moment of using them, again, whether you are assigning value or recovering it.

The calculation will apply when you access the property, since when accessing it you will go through its execution

This can be validated if you put a breakpoint in the code, when executing it will stop every time you access

You can still validate it with a simple example

UnaClase c1 = new UnaClase(10, 2);
txtResult.Text = c1.Suma.ToString();

c1.Num1 = 20;
txtResult.Text = c1.Suma.ToString();

You will see how when changing the property the sum is also affected
