Question

I am working on decoding VIN numbers into useful information and for the country they give a range of double letters (EG: SA-SM is Great Britain). How do I check to see that SG is between SA and SM? I was thinking about hex but this can’t be converted to hex because of it going past E.

Answer 1

if (String.Compare("SG","SA") > 0 && String.Compare("SG","SM") < 0)
{  // SG between SA and SM
}

Ignore case

if (String.Compare("SG","SA",true) > 0 && String.Compare("SG","SM",true) < 0)
{  // SG between SA and SM
}

You can also use one of CurrentCulture, CurrentCultureIgnoreCase, InvariantCulture, InvariantCultureIgnoreCase, Ordinal, OrdinalIgnoreCase (msdn docs)

if (String.Compare("SG","SA",CurrentCultureIgnoreCase) > 0 && String.Compare("SG","SM",CurrentCultureIgnoreCase) < 0)
{  // SG between SA and SM
}
