c# - Is there any good alternative struct for using inside switch case? -

i have switch case showing text in program. wonder can use dictionary or enum numbers , texts? or using switch case this?

string result; int number = int.parse(console.readline()); switch (number) {     case 1:         result += "ten";         break;     case 2:         result += "twenty";         break;     case 3:         result += "thirty";         break;     case 4:         result += "fourty";         break;      case 5:         result += "fifty";         break;      case 6:         result += "sixty";         break;      case 7:         result += "seventy";         break;      case 8:         result += "eighty";         break;      case 9:         result += "ninety";         break;      default:         result += "";         break; } 

it's little less verbose use dictionary{int,string} in scenario:

var dictionary = new dictionary<int, string>(9) {     {1, "ten"},     {2, "twenty"},     {3, "thirty"},     {4, "fourty"},     {5, "fifty"},     {6, "sixty"},     {7, "seventy"},     {8, "eighty"},     {9, "ninety"}, }; 

---

string dictionaryentry; if (dictionary.trygetvalue(number, out dictionaryentry)) {     result += dictionaryentry; } 

also, if plan lot of string concatenations, consider using stringbuilder instead of string result.

for routines perform extensive string manipulation (such apps modify string numerous times in loop), modifying string repeatedly can exact significant performance penalty. alternative use stringbuilder, mutable string class.
