Unreachable code detection error

[HillBilly]

What does that error mean and why would each break statement be marked as
unreachable? It implies the return will --always-- return some --thing-- if
even null and no further processing can possibly be done after the return
statement hence the break statement will not and can ever be reached?

switch (suffix)
{
case 1:
return "^st";
break;
case 21:
return "^st";
break;
case 31:
return "^st";
...
}

Yes, that's exactly what it means. How could each "return" statement
return "null" given that in each case you have a string literal? And even
if it could, why would the value it returns affect whether flow can
continue past the "return" statement?

The compiler is correctly telling you that you have "break" statements
that are unreachable. No possible configuration of input could lead to
that code being executed. That's what "unreachable" means.
