C # Reduce Abbreviations

Question

I have this code:

    if (y == a && y == b && y == c && y == d ...)
    {
        ...
    }

Is there some form of contraction so that I can rewrite it as something like that?

    if(y == (a && b && c && d ...))
    {
        ...
    }

The functionality should be exactly the same. I'm just looking for something that looks less confusing.

EDIT Sorry for not clarifying, all variables are integers. I'm looking for a shorter way to ensure that a, b, c, d, ... we are all equal y.

Answer 1

The closest thing you are going to get (without implementing your own mechanism):

if (new[] { a, b, c, d }.All(value => y == value))
    // ...

Answer 2

No , there is nothing that will simplify your code without overloading the benefits of reading with a large performance penalty.

Answer 8

For if (y == a & y == b & y == c & y == d) use:

if (y == a == b == c == d) {// code here} Strike>

For if (y == a || y == b || y == c || y == d) , and y is a simple type or string, use:

switch(y)
{
   case a:
   case b:
   case c:
   case d:
     //your code here
     break;

}

Answer 9

   bool  x=true ,y=true, z=true, p = true;

    if (x == (y == z == p)) //true

    x = false;
    if (x == (y == z == p)) //false
