Maybe the third time is a charm. This section of my csharp vs2019 class project. I get errors.

program.cs

public class Program { static void Main(string[] args) { Console.CursorVisible = false; int numberOfFruitEaten = 0; List xPosition = new List(); List yPosition = new List(); xPosition.Add(25); yPosition.Add(20); Snake snake = new Snake(xPosition, yPosition, numberOfFruitEaten); Console.SetCursorPosition(snake.XPosition[0], snake.YPosition[0]); Console.WriteLine(((char)214).ToString()); ConsoleKey playerKey = Console.ReadKey().Key; Fruit fruit = new Fruit(); Console.WriteLine(fruit); do { Console.SetCursorPosition(snake.XPosition[numberOfFruitEaten], snake.XPosition[numberOfFruitEaten]); Console.WriteLine(\" \"); bool isEaten = false; if (snake.XPosition[0] == fruit.XPosition && snake.YPosition[0] == fruit.YPosition) isEaten = true; if (isEatean) { Console.WriteLine(fruit); isEaten = false; numberOfFruitEaten++; snake.XPosition.Add(snake.XPosition[0]); snake.YPosition.Add(snake.YPosition[0]); } List xold = snake.XPosition; List yold = snake.YPosition; snake.NumberOfFruitEaten = numberOfFruitEaten; for (int j = numberOfFruitEaten; j > 0; j--) { xold[j] = xold[j - 1]; yold[j] = yold[j - 1]; } if (playerKey == ConsoleKey.LeftArrow) snake.MoveLeft(); else if (playerKey == ConsoleKey.RightArrow) snake.MoveRight(); else if (playerKey == ConsoleKey.UpArrow) snake.MoveUp(); else if (playerKey == ConsoleKey.DownArrow) snake.MoveDown(); Console.SetCursorPosition(snake.XPosition, snake.YPosition); Console.WriteLine(snake); snake.XPosition = xold; snake.YPosition = yold; if (Console.KeyAvailable) playerKey = Console.ReadKey().Key; System.Threading.Thread.Sleep(240); } while (playerKey == ConsoleKey.LeftArrow || playerKey == ConsoleKey.RightArrow || playerKey == ConsoleKey.UpArrow || playerKey == ConsoleKey.DownArrow); Console.ReadKey(); } } }
