Hi i am doing very basic c# coding where just checking odd and even number however how i can re-enter input while i am converting a string into integer at one place.

```
        if (i % 2==0) 

            {
            Console.WriteLine("even");
            Console.WriteLine("enter again", i);
        }
        else if(i%2!=0)

        {
            Console.WriteLine("odd");
            Console.WriteLine("enter again", i);
enter code here
        }

        Console.ReadKey();

```
