enum Country { Spain, USA, Japan };
static void Main(string[] args)
{
Country country;
Console.WriteLine("Enter the number of country
1.Spain
2.The USA

string input = Console.ReadLine();
bool sucess = Enum.TryParse<Country>(input, out country);

if (!sucess)
{
Console.WriteLine("entry {0} is not a valid country", input);
return;
}

switch (country)

case Country.Spain:
Console.WriteLine("Its in Europe");
break;
case Country.USA:
Console.WriteLine("Its in North America");
break;
case Country.Japan:
Console.WriteLine("Its in Asia");
