我试图得到
Console.WriteLine("Please enter a day of the week, e.g. Tue: ");
today = Console.ReadLine();
GotoWork = string (today != SUN && today != SAT) ?
Console.WriteLine("You have to go to work today...") ;
Console.WriteLine("Ahh... the weekend. No work!");'
编译并告诉我是否需要上班,但它告诉我'(today != SUN && today != SAT)' 是
invalid expression term for string.
