Ternary operators in C#

Question

With the ternary operator, it is possible to do something like the following (assuming Func1() and Func2() return an int:

int x = (x == y) ? Func1() : Func2();

However, is there any way to do the same thing, without returning a value? For example, something like (assuming Func1() and Func2() return void):

(x == y) ? Func1() : Func2();

I realise this could be accomplished using an if statement, I just wondered if there was a way to do it like this.

Answer 1

Weird, but you could do

class Program
{
    private delegate void F();

    static void Main(string[] args)
    {
        ((1 == 1) ? new F(f1) : new F(f2))();
    }

    static void f1()
    {
        Console.WriteLine("1");
    }

    static void f2()
    { 
        Console.WriteLine("2");
    }
}

Answer 2

I don't think so. As far as I remember, the ternary operator is used in an expression context and not as a statement. The compiler needs to know the type for the expression and void is not really a type.

You could try to define a function for this:

void iif(bool condition, Action a, Action b)
{
    if (condition) a(); else b();
}

And then you could call it like this:

iif(x > y, Func1, Func2);

But this does not really make your code any clearer...
