C#. Do if( a == (b or c or d)). Is it possible?

Question

Is there another way to write something like this:

if (a == x || a == y || a == z)

One way that I found is doing it like this:

Answer 1

For instance, your logic is like that:

if(a==x || a== y|| a==z)
{
    DoSomething();
} 
else
{
   DoOtherThings();
}

will equivalent to:

if(a!=x&& a != y && a!= z)
{
   DoOtherThings();
}
else
{
   DoSomething();
}

Cheers.
