我正在开发一个基于文本的游戏以适应 C#，我将如何循环 if 语句，以便如果用户不输入是或否，它会写入“无效输入，重试”并从第一个“Console.WriteLine()”

这可能是一种解决方案：

while( true )
{
    Console.WriteLine( "Your answer?..." );
    var answer = Console.ReadLine();

    if (answer == "yes")
    {
        Console.ForegroundColor = ConsoleColor.Green;
        Console.WriteLine("\nGreat :)\n");
        Console.ForegroundColor = ConsoleColor.Gray;
        break;
    } 
    else if (answer == "no")
    {
        Console.ForegroundColor = ConsoleColor.Red;
        Console.WriteLine("\nTOO BAD\n");
        Console.ForegroundColor = ConsoleColor.Gray;
        break;
    }    
    else 
    {
        Console.WriteLine("invalid input, try again\n");
    }
}
