Validate user input in Console App

Guest User

Hi...How can I validate user input when the user's input is greater than 10.

I mean, in this code below if the user introduce a value greater than 10, I want to print a message on screen. What operator or comparision should I use and where?..Here is the code:

********************************************************

private static void GusssingGame()

{

Console.Clear();

Console.WriteLine(" ***** GUESS THE NUMBER GAME ******");

Random myRandom = new Random();

int randomNumber = myRandom.Next(1, 11);

int intentos = 0;

bool incorrect = true;

{

Console.Write("Choose a number between 1 and 10 and press ENTER: ");

string result = Console.ReadLine();

intentos++;

if (result == randomNumber.ToString())

{

incorrect = false;

}

else

{

Console.WriteLine("Incorrect. Try again!");

}

} while (incorrect == true);

*************************************************************

For your scenario, I think adding and if-else statement should do the trick. See below.
private static void GusssingGame()
       {
           Console.Clear();
           Console.WriteLine(" ***** GUESS THE NUMBER GAME ******");
           Random myRandom = new Random();
           int randomNumber = myRandom.Next(1, 11);
           int intentos = 0;
           int userInput = 0; //added

           bool incorrect = true;
           do
           {
               Console.Write("Choose a number between 1 and 10 and press ENTER: ");
               string result = Console.ReadLine();

//userinput to int
               int.TryParse(result, out userInput);

//prevent non numeric/numbers
               if (userInput == 0)
               {
                   Console.WriteLine("number only !!");
               }
//check if number > 10
               else if (userInput > 10){
                   Console.WriteLine("input is greater than 10");
               }
               else
               {
                   intentos++;
                   if (result == randomNumber.ToString())
                   {
                       Console.WriteLine("Good job!"); //display victory message
                       Console.ReadLine(); //press enter to exit
                       incorrect = false;
                   }
                   else
                   {
                       Console.WriteLine("Incorrect. Try again!");
                   }
               }
           } while (incorrect == true);
       }
