One reason that the designers c# might have chosen to NOT have enums auto convert was to prevent accidentally mixing different enum types...
e.g. this is bad code followed by a good version
enum ParkingLevel { GroundLevel, FirstFloor};
enum ParkingFacing { North, East, South, West }
void Test()
{
var parking = ParkingFacing.North; // NOT A LEVEL
// WHOOPS at least warning in editor/compile on calls
WhichLevel(parking);
// BAD wrong type of index, no warning
var info = ParkinglevelArray[ (int)parking ];
}
// however you can write this, looks complicated
// but avoids using casts every time AND stops miss-use
void Test()
{
ParkingLevelManager levels = new ParkingLevelManager();
// assign info to each level
var parking = ParkingFacing.North;
// Next line wrong mixing type
// but great you get warning in editor or at compile time
var info=levels[parking];
// and.... no cast needed for correct use
var pl = ParkingLevel.GroundLevel;
var infoCorrect=levels[pl];
}
class ParkingLevelInfo { /*...*/ }
class ParkingLevelManager
{
List<ParkingLevelInfo> m_list;
public ParkingLevelInfo this[ParkingLevel x]
{ get{ return m_list[(int)x]; } }}
