C#: Find the first two-digit number equal to the square of the number of its units, with a dozen cc.

Use the operator while, no do. I tried and only did it with a do/while:

        var random = new Random();
        int x, y;
        do
        {
            x = random.Next(1, 9);
            y = random.Next(1, 9);
        }
        while (x * 10 + y != x * x * x + y * y);
        Console.WriteLine($"{x}{y}");

Please redesign this code to the cycle while.

let x = 1, y = -1;
while (x * 10 + y != x * x * x + y * y && x < 10) {
  y++;
  if (y == 10) {
    y = 0;
    x++;
  }
}
console.log(x == 10? "No number" : `${x}${y}`);
