It stands for “ordinal”. The earliest use of ord that I remember was in Pascal. There, ord() returned the ordinal value of its argument. For characters this was defined as the ASCII code. The same convention was also used in Modula-2. Later, Python (as well as PHP, some dialects of SQL etc) followed this convention, … Read more
Per that standard [dcl.enum] The enumeration type declared with an enum-key of only enum is an unscoped enumeration, and its enumerators are unscoped enumerators. The enum-keys enum class and enum struct are semantically equivalent; an enumeration type declared with one of these is a scoped enumeration, and its enumerators are scoped enumerators. The optional identifier … Read more

Try MyEnum.values()[x] where x must be 0 or 1, i.e. a valid ordinal for that enum. Note that in Java enums actually are classes (and enum values thus are objects) and thus you can’t cast an int or even Integer to an enum.
InvariantCulture Uses a “standard” set of character orderings (a,b,c, … etc.). This is in contrast to some specific locales, which may sort characters in different orders (‘a-with-acute’ may be before or after ‘a’, depending on the locale, and so on). Ordinal On the other hand, looks purely at the values of the raw byte(s) that … Read more
