Question

我正在创造一个tic tac toe游戏，并且对于该游戏部分我正在得到一个其他术语的invaild表达，任何人都可以帮忙吗？它在我添加介绍程序之前有效提前致谢

static void playAgainMsg(String message)
    {
        Console.WriteLine(message + "Do you want to play again? Y/N"); // Displaying the resukt of the game and asking the user if they would like to play again and tells them to input Y or N
        if 
        {
            (Console.ReadLine().Equals("Y")) // This reads the line to check the user input
            strPlaysAgain.Equals("Y");
            introduction(); <---- worked before this was added...
        }   
        else
        {
            strPlaysAgain.Equals("N"); // This Changes the value from the default value of Y to N so that it exits the While loop for PlaysAgain.
            Console.Clear(); //Clears the console so that the game board is removed.
            MainMenu();  // returns the user back to the introduction -  edit to be main menu with an exit feature, highscores
        }
    }

Answer 1

您不会使用if测试任何内容。另外，str1.Equals(str2)是一个测试。您必须使用=来分配值。

static void playAgainMsg(String message)
        {
            Console.WriteLine(message + "Do you want to play again? Y/N"); 
            if (Console.ReadLine().Equals("Y"))
            {
                strPlaysAgain = "Y";
                introduction();
            }   
            else
            {
                strPlaysAgain = "N"; 
                Console.Clear(); removed.
                MainMenu();  
            }
        }

Answer 2

你错位了条件

        if (Console.ReadLine().Equals("Y")) //<------------
        {
             // This reads the line to check the user input
            strPlaysAgain.Equals("Y");
            introduction();
        }   
        else
        {
            strPlaysAgain.Equals("N"); // This Changes the value from the default value of Y to N so that it exits the While loop for PlaysAgain.
            Console.Clear(); //Clears the console so that the game board is removed.
            MainMenu();  // returns the user back to the introduction -  edit to be main menu with an exit feature, highscores
        }

term else的表达式无效
