set with different values

hey everyone, i am a total noob and i want to ask if there is a way for set having different values with different conditions? like

private bool Bool1;

public bool Bool2
{
   get => Bool1;
   if (a = 1) {
      set => Bool2 = true;
   }
   else {
      set => Bool2 = false;
   }
}

private bool Bool1;

public bool Bool2
{
   get => Bool1;
   if (a = 1) {
      set => Bool2 = true;
   }
   else {
      set => Bool2 = false;
   }
}

even if they did it will throw stack overflow exception

Pobiega•9mo ago

its also violating "the rule of least surprise" a setter not setting a value I give it is very surprising

TheRanger•9mo ago

private bool Bool1;

public bool Bool2
{
   get => Bool1;
   set
   {
      if (a == 1) 
      {
        Bool1 = true;
      }
      else 
      {
        Bool1 = false;
      }
   }
}

private bool Bool1;

public bool Bool2
{
   get => Bool1;
   set
   {
      if (a == 1) 
      {
        Bool1 = true;
      }
      else 
      {
        Bool1 = false;
      }
   }
}

Honestly ig, it is better to extract that logic to a method…I don’t think it should be the job of setters

TheRanger•9mo ago

it is, thats one of the main reasons properties exist

invalidkit0OP•9mo ago

nah i just have a code that requieres setters sorry if i spelt it wrong

Pobiega•9mo ago

x.Bool2 = true;
if(x.Bool2) // this wont run????

x.Bool2 = true;
if(x.Bool2) // this wont run????

this would be a potential result from the above and make me throw your code in the nearest garbage bin

😔

Pobiega•9mo ago

if I set it to true, and thats not allowed, throw an exception dont silently set it to false instead

TheRanger•9mo ago

setting Bool2 to false or true wont make a difference, because your setter never reads the value

Vi Ness•9mo ago

Based on the code given, my interpretation was they wanted something more akin to

private int a;

public bool Bool1
{
    get => (a == 1);
}

private int a;

public bool Bool1
{
    get => (a == 1);
}

But they said the code requires setters so idk

Pobiega•9mo ago

yeah, which absolutely fucks with your expectations if I set it to true, I expect it to be true, or throw an exception

Alen Alex•9mo ago

I too somehow agree with that, silently modifying it internally will be a disaster sometimes Yes, I would expect it to compute the value based on the input (value that I set), not based on some random value a. If I set Bool2 = true and the state got changed due to some other random variable seems a bit off for me. I don't think thats an actual behaviour of setter.
