How to implement a switch here instead of if's and else if's?

I’m using if/else statements to check which radio button is clicked. How to use a switch statement instead of if/else.

else if (CBLeather.Checked && CBComputerNav.Checked && !CBStereo.Checked) {
    accessories = Accessories.LeatherAndNavigation;
} else if (CBComputerNav.Checked && CBLeather.Checked && CBStereo.Checked) {
    accessories = Accessories.All;
} else {
    accessories = Accessories.None;
}

Although your use case is not meant for a switch statement but there is a crazy way of doing so :)

switch (0)
{
    case 0 when (CBLeather.Checked && CBComputerNav.Checked && !CBStereo.Checked):
        accessories = Accessories.LeatherAndNavigation;
        break;
    case 0 when (CBComputerNav.Checked && CBLeather.Checked && CBStereo.Checked):
        accessories = Accessories.All;
        break;
    default:
        accessories = Accessories.None;
        break;
}

Again, it works but not advisable!

You cannot put switch case here i think as you have multiple condition for code branching.

You can extract methods from these conditions and just call them in your if blocks something like:

private bool IsLeatherAndNavigation()
{
   return CBLeather.Checked && CBComputerNav.Checked && !CBStereo.Checked;
}

and use :

if (IsLeatherAndNavigation()) 
{
   accessories = Accessories.LeatherAndNavigation;
}

and can be reused wherever required instead of putting the duplicated if conditions everywhere around in the class.
