Multi-variable switch statement in C#

Question

I would like use a switch statement which takes several variables and looks like this:

switch (intVal1, strVal2, boolVal3)
{
   case 1, \"hello\", false:
            


        

Answer 1

You could convert to a string:

switch (intVal1.ToString() + strVal2 + boolVal3.ToString())
{
   case "1helloFalse":
      break;
   case "2worldFalse":
      break;
   case "2helloFalse":

   etc ....
}

I think the question that comes to play, though is whether or not there's a better way of defining the logic. For instance, let's say you're trying to figure out who knows superman. We could do the check like this:

switch (first + last)
{
   case "ClarkKent":
   case "LoisLane":
      // YES
      break;
   default;
      // Sadly, no
      break;
}

But what happens when you get some other guy named Clark Kent? Really couldn't you have some other value that you determine this logic based on, ie bool KnowsSuperman?

The idea being, a switch statement is used to determine logic based off a single set of choices. If there are multiple values you're trying to switch off of, then the logic could get insanely difficult to maintain down the line.

Another example would be if you need to group people into several groups and perform some logic depending on the group they're in. You could code it up to say, if you're Bob, Jeff, Jim, or Sally, you're in group A, but what if you need to add someone else to group A? You'd have to change the code. Instead, you could create an extra property called Group, which could be an enum or string, which you could use to specify which group someone is in.
