c# - A btter way to represent Same value given multiple values(C#3.0) -

i have situation looking more elegant solution.

consider below cases

"bkp","bkp","book-to-price" (will represent) book-to-price  "aop","aspect oriented program" (will represent) aspect-oriented-program 

i.e. if user enter bkp or bkp or book-to-price , program should treat book-to-price. same holds second example(aspect-oriented-program).

i have below solution:

solution:

if (str == "bkp" || str == "bkp" || str == "book-to-price" ) return "book-to-price". 

but think there can many other better solutions .

could people please give suggestion.(with example better)

i using c#3.0 , dotnet framework 3.5

i consider using dictionary<string,string>, perhaps populated configuration file or database table, alias canonical name relationships. use case insensitive key comparer. example,

var map = new dictionary<string,string>( stringcomparer.ordinalignorecase ); map.add( "bkp", "book-to-price" ); map.add( "book-to-price", "book-to-price" ); map.add( "aop", "aspect-oriented-program" ); map.add( "aspect oriented program", "aspect-oriented-program" ); 

then need, given, key o(1) lookup find canonical name.

var name = map["bkp"];
