Selamat Pagi, Selamat Sore, Selamat Malam... itu adalah yang dihasilkan dari kode dibawah ini

public enum enLanguage { Indonesian = 0, English = 1 }

public static string Greetings(enLanguage bahasa)
{
   string timeSpeak = "";
   if (DateTime.Now.Hour >= 0 && DateTime.Now.Hour < 11)
   {
       switch (bahasa)
       {
           case enLanguage.Indonesian:
               timeSpeak = "pagi";
               break;

           case enLanguage.English:
               timeSpeak = "morning";
               break;
       }
   }
   else if (DateTime.Now.Hour >= 11 && DateTime.Now.Hour < 15)
   {
       switch (bahasa)
       {
           case enLanguage.Indonesian:
               timeSpeak = "siang";
               break;

           case enLanguage.English:

               break;
       }
   }
   else if (DateTime.Now.Hour >= 15 && DateTime.Now.Hour < 19)
   {
       switch (bahasa)
       {
           case enLanguage.Indonesian:
               timeSpeak = "sore";
               break;

           case enLanguage.English:

       {
           case enLanguage.Indonesian:
               timeSpeak = "malam";
               break;

           case enLanguage.English:
