C# 中的三元运算符混淆

Question

can someone explain me how this line of C# code is calculated?

int myInt = false? true ? 0 : 1 : 2; // ans = 2

Answer 1

Let's add parenthesis for the line being more readable :

int myInt = false ? (true ? 0 : 1) : 2;

Now let's compute the values. For inner ?: we have

(true ? 0 : 1)

Which equals to 0 . Then outer ?: will be

int myInt = false ? 0 : 2;

which equals to 2
