c#猜谜游戏，只有X次尝试

这基本上是我的第一个小c#程序。我建立了一个"规则"，所以你只有20次尝试猜测正确的数字。我想知道是否有一种更漂亮的方式来实现这个"规则"。

这是我的代码:

        bool run = true;

        while (run == true) // Main While Schleife
        {
            Random rndnr = new Random();
            int rnd;
            rnd = rndnr.Next(1, 100);
            int guess;
            int trys;
            trys = 0;
            guess = 0;

            Console.WriteLine("Can you guess my number? I am thinking about a number between 1 and 100!");
            guess = Convert.ToInt32(Console.ReadLine());
            Console.WriteLine(rnd);
            while (guess != rnd)
            {

                if (trys > 20)
                {
                    Console.Clear();
                    Console.WriteLine("You only have 20 trys. You failed! 'n");
                    run = false;
                    Console.WriteLine("Do you wann play again? Press R + Enter to play again!");
                    string rerun = Console.ReadLine().ToUpper();
                    if (rerun == "R")
                    {
                        run = true;
                        trys = 0;
                        Console.Clear();
                        break;
                    }
                    else
                    {
                        run = false;
                        break;
                    }

                }


            if (guess > rnd)
            {
                Console.WriteLine("My number is lower than" + guess + "'n guess again >>");
                guess = Convert.ToInt32(Console.ReadLine());
            }
            if (guess < rnd)
            {
                Console.WriteLine("My number is higher than" + guess + "'n guess again >>");
                guess = Convert.ToInt32(Console.ReadLine());
            }
            if (guess == rnd)
            {
                Console.Write("You guessed right my number is" + rnd + "and you needed " + trys + "trys");
                run = false;
                Console.WriteLine("Do you wann play again? Press R + Enter to play again!");
                string rerun = Console.ReadLine().ToUpper();
                if (rerun == "R")
                {
                    run = true;
                    trys = 0;
                    Console.Clear();
                }
                else
                {
                    run = false;
                    break;
                }
            }

            trys++;
            }


        }
        Console.Clear();
        Console.WriteLine("Thanks for palying see you next time!");

            }
