我很想尝试编程，我甚至不确定如何正确地提出我的问题。我有一个错误，阻止我在离开程序时向用户显示随机卡号。 （见第21行：Console.WriteLine("\n" + "Your lucky card For today is: " + yourCard[luckyFiftyTwo]));数组，随机函数等都包含在“获取财富”的方法中。
我可以将方法切片，然后放入两个随机化器，但是这会让我重复一行代码来做到这一点，在我看来我应该能够调用实例（我是不知道如果我说的正确，请随时纠正我，我真的想学习 - 谢谢你）当有人退出该计划时。所以我需要能够将'yourCard [luckyFiftyTwo]'的结果从getFortune方法中传递出来，并在magic8ball方法中进行/ make访问。
感谢任何帮助。我希望我已经解释了我想要做的事情。再一次，我真的很愚蠢，并试图做超出我老师要求的范围的事情 - 我认为这是一个很好的学习方法（我们甚至还没有使用数组 - 我可以用breakCase语句来做所有事情，但我认为阵列会更清晰/更紧凑。）
我现在在胡说八道。请帮助。
代码如下：
using System;

//test in chunks
public void Magic8ball()
{
Console.WriteLine(" - - - - - - - - = = = = Wisdom of Magic 8 Ball = = = = - - - - - - - - \n \n ");
Console.WriteLine("Would you like to consult the wisdom of the Magic 8 Ball? \n");
PlayAgain();//we do here to ask if they want to play (Y)(N)(?)
do
{
GetFortune();
} while (PlayAgain()); //while they keep wanting to play
Console.WriteLine("Thank you for consulting the wisdom of the Magic 8 Ball.");
Console.WriteLine("\n" + "Your lucky card For today is: " + yourCard[luckyFiftyTwo]);
}
public Boolean PlayAgain()
{
Console.WriteLine("\n" + "Please enter \"Y\" to play, or \"N\" If you would prefer not to continue to play.");
String command = Console.ReadLine().ToLower(); //Read in data
if (command == "y") return true;

Console.WriteLine("\n" + "What was that? I'm sorry but the Magic 8 Ball didn't understand your entry.");
return false;

执行此操作的一种方法是让GetFortune()返回最后一个结果 - 将其保存在局部变量中：
string lastCard;
do
{
lastCard = GetFortune();
} while (PlayAgain()); //while they keep wanting to play
Console.WriteLine("Thank you for consulting the wisdom of the Magic 8 Ball.");
Console.WriteLine("\n" + "Your lucky card For today is: " + lastCard);
GetFortune()应如下所示：
public string GetFortune() //produces random results
{
// ...
return yourCard[luckyFiftyTwo];
}
作为一边（语法）注释，您可以使用内联语法初始化数组，如下所示：
String[] responses = new String
{
"It is certain.",
"It is decidedly so.",
"Yes definitely.",
"You may rely on it.",
// etc
};
