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

You can accomplish this with an extension method.

public static bool In(this T obj, params T[] collection) {
   return collection.Contains(obj);
}

Then...

if(index.In(7,8))
{
    ...
}
