Is there a ternary operator to run a function in c#?

Question

In C# I know you can do things like this:

int number = true ? 1 : 0;

This returns the left or right side depending on if the Boolean is true or not.

But is there a way to do the same thing but instead run a function instead of returning a value? Something like this:

This doesn't work (I get multiple syntax errors)

WPS.EDIT_MODE ? ExecuteEditMode() : ExecutePublicMode();

Thanks.

Answer 1

The conditional operator must return a value. Assuming the functions don't both return a meaningful value for you, you should use an if statement to do that:

if(someCondition)
    doA();
else
    doB();

Although technically you could use an anonymous function to do this if you really wanted:

int number = someCondition ?
    new Func<int>(() => { doA(); return 0; })() :
    new Func<int>(() => { doB(); return 1; })();

but that's not suggested; using an if/else is both easier and more readable for that case.

Answer 2

If both functions return an int, yes.

The ternary operator is about returning values. Not returning values doesn't make sense.

The conditional operator (?:) returns one of two values depending on the value of a Boolean expression.
