namespace ConsoleApplication2
{
class Program
{
static void Main()
{
Console.WriteLine("Welcome to our Multiplex");
Console.WriteLine("We are presently Showing:");
Console.WriteLine("1.Legend");
Console.WriteLine("2.Macbeth");
Console.WriteLine("3.Everest");
Console.WriteLine("4.A Walk In the Woods");
Console.WriteLine("5.Hotel Transylvania");
Console.WriteLine("Enter the number of the film you wish to see?");

string moviestring = Console.ReadLine();
int movie = int.Parse(moviestring);
以下是我可以为您的案例建议的解决方案:
static void Main(){
bool flag0 = true; //initialize tracking bool value to exit loop when needed
int result;
Console.WriteLine("Welcome to our Multiplex");
Console.WriteLine("We are presently Showing:");
Console.WriteLine("1.Legend");
Console.WriteLine("2.Macbeth");
Console.WriteLine("3.Everest");
Console.WriteLine("4.A Walk In the Woods");
Console.WriteLine("5.Hotel Transylvania");
do //do while loop suits this case best as it does check the value on the end
{
Console.WriteLine("Enter the number of the film you wish to see?");
string moviestring = Console.ReadLine();
int.TryParse(moviestring, out result); //does try-catch check so it wont crash on the run-time
if (result <= 5 && result >= 1) //logical check if value is correct
flag0 = false; //exits the loop
//do true logic....
else
Console.WriteLine("Incorrect value. Try again.");
//do false logic
} while (flag0);
}
