如何将 bool 转换为 int？

Question

My code looks like this:

if (Settings.adp == true)
   App.DB.UpdateIntSetting(SET.Adp, 0);
else
   App.DB.UpdateIntSetting(SET.Adp, 1);

Is there a way I could get this down to one line by somehow converting the bool Settings.adp into an int (0 or 1)

Answer 1

You can use the ternary operator to consolidate it to one line:

App.DB.UpdateIntSetting(SET.Adp, Settings.adp ? 0 : 1);

From the documentation

condition? consequence: alternative

Answer 2

With your reversed logic, Nathan's ternary operator answer is probably the best option for clarity, but you could also use Convert.ToInt32 :

bool negatedValue = !Settings.adp;
App.DB.UpdateIntSetting(SET.Adp, Convert.ToInt32(negatedValue));

Answer 3

Your situation looks like a good candidate for using ValueObject , provided that you need to perform that conversion to int in many places in your project.

Reason: If you are not using ValueObject you will end up duplicating that logic for conversion to int all over your application. And ValueObject is even more suited for your case because of your inverted logic (true -> 0, false -> 1). Using ValueObject will help you avoid duplication of this logic.
