Using GetHashCode for getting Enum int value

Is it safe to use GetHasCode to get a enumeration value like the code below:

myList.SelectedIndex = myEnumValue.GetHashCode()

Answer 1

No. The result isn’t guaranteed to be unique or equivalent to the integral value of that enum value.

I think it is currently implemented to be the same as a cast to int. But that’s an implementation detail and may change at any time.

The correct way is to cast to the underlying integral type:

myList.SelectedIndex = (int)myEnumValue;
