While loop not producing correct results

Question

I am trying to use a while-loop to ask the user for a number between 1 and 10. While the user fails to enter a number between 1 and 10 (inclusive), I want to ask them for another number.

My code so far is:

int i = 0;
Console.WriteLine("Enter a number.");
while (i <= 10)
{
    Console.ReadLine();

    if (i > 1 && i < 10)
    {
        Console.ReadLine();
        continue;
    }

    if (i < 1 && i > 10)
    {
        Console.WriteLine("Enter New Number...");
        break;
    }

    Console.ReadLine();
}

What am I doing wrong?

Answer 1

You're writing if (i < 1 && i > 10).
i can never be both less than 1 and more than 10.
(Hint: 'and' is the wrong word)

Also, you never assigned a value to i.
(Hint: call int.Parse)

Also, you probably want to swap break (which stops looping) and continue (which continues looping)

Also, what should the condition in the while loop be?

Answer 2

int i = 0;
while (i < 1 || i > 10)
{
    int.TryParse(Console.ReadLine(),out i);
}

or with text

int i = 0;
Console.WriteLine("Enter a number");
int.TryParse(Console.ReadLine(),out i);
while (i < 1 || i > 10)
{
    Console.WriteLine("Try Again");
    int.TryParse(Console.ReadLine(),out i);
}
