C#如何在另一个程序中使用程序中的字符串

我在练习一些代码

我有这个密码

班级计划

{

    static void Main(string[] args)

    {

        Program a = new Program();
        a.Alalao();
        Program b = new Program();
        b.Game();
    }
    public void Alalao()
    {
        Console.WriteLine("Hello my dear. How would you like to be called?");
        string n1 = Console.ReadLine();
        // more code
    }
    public void Game()
    {
        Console.WriteLine("This is a game where you have answer questions. For each correct answer 1 get an point and for each wrong answer you lose a point.");
        Console.WriteLine("You will start with 5 points. Consider it as a courtesy");
        Console.WriteLine("{0}, are you ready start?", n1);
    }
}

如何将Alalao（）中的字符串n1放入游戏（）中的最后一个命令Console.writeline中

提前谢谢。

有多种可能的方法。一种解决方案是使用参数/返回值

static void Main(string[] args)
{

    Program a = new Program();
    var name = a.Alalao();
    Program b = new Program();
    b.Game(name);
}

public string Alalao()
{
    Console.WriteLine("Hello my dear. How would you like to be called?");
    string n1 = Console.ReadLine();
    // more code

    return n1;
}
public void Game(string n1)
{
    Console.WriteLine("This is a game where you have answer questions. For each correct answer 1 get an point and for each wrong answer you lose a point.");
    Console.WriteLine("You will start with 5 points. Consider it as a courtesy");
    Console.WriteLine("{0}, are you ready start?", n1);
}

这就是结构化编程的全部内容，您可以将较大的问题划分为较小的块（方法），但仍然可以使用参数和返回值来传达这些块

static void Main(string[] args)
{

    Program a = new Program();
    var name = a.Alalao();
    Program b = new Program();
    b.Game(name);
}

public string Alalao()
{
    Console.WriteLine("Hello my dear. How would you like to be called?");
    string n1 = Console.ReadLine();
    // more code

    return n1;
}
public void Game(string n1)
{
    Console.WriteLine("This is a game where you have answer questions. For each correct answer 1 get an point and for each wrong answer you lose a point.");
    Console.WriteLine("You will start with 5 points. Consider it as a courtesy");
    Console.WriteLine("{0}, are you ready start?", n1);
}

从Alalao返回n1并将其作为参数添加到游戏中。就像这样

public string Alaloa () {
  // ...
  string n1 = Console.ReadLine();
  // ...
  return n1;
}

// ...

public void Game (string inString) {
  // ..
  Console.WriteLine("{0}, are you ready start?", inString);
}

然后需要将Alaloa的返回值保存为变量，并将其添加到主方法中的游戏调用中，如下所示

static void Main (string[] args) {
  Program a = new Program();
  string myString = a.Alaloa(); // Saving the string to a variable
  
  Program b = new Program();
  b.Game(myString);
}
