If I am to write this piece of code, it works fine with the normal 'if-else' layout.
if(isOn)
{
i = 10;
}
else
{
i = 20;
}
Although I am unsure how to convert this using the ternary operator
isOn = true ? i = 1 : i = 0;
Error: Type of conditional expression cannot be determined because there is no implicitly conversion between 'void' and 'void'.
EDIT:
Answer = i = isOn ? 10 : 20;
Is it possible to do this with methods?
if(isOn)
{
foo();
}
else
{
bar();
}
Please try the following. BTW, it only works for value assignments not method calls.
i = isOn ? 10 : 20;
Reference:
void methods into lambda returning fake value for purely theoretical way of using ?: with void functions.You may simply try this:
i = isOn? 10:20
The MSDN says:
The condition must evaluate to true or false. If condition is true, first_expression is evaluated and becomes the result. If condition is false, second_expression is evaluated and becomes the result. Only one of the two expressions is evaluated.
EDIT:-
If you want to invoke void methods in a conditional operator, you can use delegates else it is not possible to use ternary operators for methods.
And if your methods are returning something then try like this:
i = isOn ? foo() : bar(); //assuming both methods return int
You're on the right track but a little off.
i = isOn ? 10 : 20;
Here 10 will be assigned to i if isOn == true and 20 will be assigned to i if isOn == false
Here's an explanation that might help. The statement you're looking for is:
i = isOn ? 10 : 20;
And here's what that means:
(result) = (test) ? (value if test is true) : (value if test is false);
try the following
i = isOn ? 10 :20
Try the following:
i = isOn ? 10 : 20
You need:
i = true ? 10 : 20;
where true is your condition.
isOn is the bool (condition) specified in OP's code
true part was just for the OP to replace it with the condition.
ifclear enough ? also it depends what these methods are returning. If they are not returning anythingvoidthen I believe you can't use the ternary operators.
