Combining multiple conditional expressions in C#

Question

In C#, instead of doing if(index == 7 || index == 8), is there a way to combine them? I\'m thinking of something like if(index == (7, 8)).

Answer 1

Do u need something like that

        int x = 5; 

        if((new int[]{5,6}).Contains(x)) 
        {
            Console.WriteLine("true");


        }
        Console.ReadLine();
