更快些：if语句或条件运算符？ （C＃）

Question

Simple question (I think): Which of these pieces of code would execute faster in C#?

newSpeed = newSpeed > maxSpeed ? maxSpeed : newSpeed;

or

if (newSpeed > maxSpeed)
{
    newSpeed = maxSpeed;
}

Answer 1

I am guessing the second would be faster, in some cases, as it does not always do an assignment, whereas the first always does an assignment.

Eg, when newSpeed <= maxSpeed , no assignment is done, only a comparison.

Answer 2

In this instance the compiler takes the ternary line and creates an if statement... so it turns on to be the exact same thing.

Answer 3

You need as justnS said, ternary operators will be converted to if statements, while compiling, but if your using a ternary operator, you will need an if and an else part, while the if statement has no else. So maybe there will be a noticeable difference, if you run the code a few million or billion times. But it does not matter, if your building a normal program.
