Question

Does anyone know if it’s possible to include a range in a switch statement (and if so, how)?

For example:

switch (x)
{
   case 1:
     //do something
     break;
   case 2..8:
     //do something else
     break;
   default:
     break;
}

The compiler doesn’t seem to like this kind of syntax – neither does it like:

case <= 8:

No, this isn’t possible. There are a few ways I’ve done this in the past:

Fixed coding:

switch (x)
{
   case 1:
     //do something
     break;
   case 2:
   case 3:
   case 4:
   case 5:
   case 6:
   case 7:
   case 8:
     //do something else
     break;
   default:
     break;
}

In combination with an if {} statement:

switch (x)
{
   case 1:
     //do something
     break;
   default:
     if (x <= 8)
     {
        // do something
     }
     else
     {
       // throw exception
     }
     break;
}
