Enum item mapped to another value

Enum item mapped to another value

I have enum:
enum MyEnum{
aaaVal1,
aaaVal2,
aaaVal3,
}
I need to have abbreviated version of 'MyEnum' which maps every item from
'MyEnum' to different values. My current approach is method which simply
translates every item:
string translate(MyEnum myEnum)
{
string result = "";
switch ((int)myEnum)
{
0: result = "abc";
1: result = "dft";
default: result = "fsdfds"
}
return result;
}
the problem with this approach is that every time programmer changes
MyEnum he should also change translate method.
This is not a good way of programming.
So..
Is there any more elegant solution for this problem?
Thank you :-)
