如何使用变量'；s采用不同的方法

本文关键字：方法 变量 何使用 | 更新日期: 2023-09-27 18:24:46

我正在C#中编写一个程序，控制台应用程序和我遇到了一个问题。

到目前为止，我已经得到了五个类：主类Program和其他四个Teacher、Student、Course、Class。

我的问题是，我从用户那里收到信息，而这些信息都是用另一种方法。

我希望能够使用我从用户那里得到的输入，并用不同的方法来编辑输入。

简单地说程序应该能够编辑输入，而我却无法使其工作？！？这是我写的代码：

struct Students
{
   public string name;
   public string family;
   public int ID;
   public string Major;
   public int studentCode;
} 
class Student
{
    public static void ShowStudent() 
    {
        Console.Clear();
        Console.WriteLine("This is Student's Section:'n");
        Console.WriteLine("====================================");
        Console.WriteLine("Enter the Number Of the Section you want to Work with:'n");
        Console.WriteLine("1 Submit");
        Console.WriteLine("2 Edit");
        Console.WriteLine("3 Back");
        string choice = Console.ReadLine();
        switch (choice)
        {
            case "1":
                ReciveStudent();
                break;
            case "2":
                break;
            case "3":
                Program.mainShow();
                break;
            default:
                Console.Clear();
                Console.WriteLine("Please Enter INrange Number.'nPress any Key to Continue....");
                Console.ReadKey();
                ShowStudent();
                break;
        }
    }
    public static void ReceiveStudent()
    {
        Console.Clear();
        int n;
        Console.WriteLine("How Many Student's you Want to Enter?");
        n = Convert.ToInt32(Console.ReadLine());
        Students[]  st = new Students[n];
        for (int i = 0; i < n; i++)
        {
            Console.WriteLine("Enter Student ID:");
            st[i].ID = Convert.ToInt32(Console.ReadLine());
            Console.WriteLine("Enter Student CODE:");
            st[i].studentCode = Convert.ToInt32(Console.ReadLine());
            Console.WriteLine("Enter Student Name:");
            st[i].name = Console.ReadLine();
            Console.WriteLine("Enter Student Family:");
            st[i].family = Console.ReadLine();
            Console.WriteLine("Enter Student Major:");
            st[i].Major = Console.ReadLine();                         
        }
        ShowStudent();
    }
}

主要调用ShowStudent()方法，即program.cs（void main）。

我想在不同的方法中使用数组值。

感谢任何评论。。。

谢谢大家。

如何使用变量'；s采用不同的方法

返回方法RecieveStudent从用户处收集的数据，并将这些数据用作另一个方法的输入。

将接收学生更改为：public static Students[] RecieveStudent()

public static Students[] RecieveStudent() {
    // your code here as is
    return st;
}

并使用返回的数组作为其他方法的输入：

Students[] students = ReceiveStudent();
otherMethod(students) // Do other work on data

顺便说一句，你的命名可能需要一些工作。例如，你的结构Students实际上并没有为一组学生建模，而是只为一个学生建模。

编辑：

struct Students
{
   public string name;
   public string family;
   public int ID;
   public string Major;
   public int studentCode;
} 
class Student
{
    public static void ShowStudent() 
    {
        Console.Clear();
        Console.WriteLine("This is Student's Section:'n");
        Console.WriteLine("====================================");
        Console.WriteLine("Enter the Number Of the Section you want to Work with:'n");
        Console.WriteLine("1 Submit");
        Console.WriteLine("2 Edit");
        Console.WriteLine("3 Back");
        string choice = Console.ReadLine();
        Students[] students = null;
        switch (choice)
        {
            case "1":
                students = ReciveStudent();
                break;
            case "2":
                break;
            case "3":
                Program.mainShow();
                break;
            default:
                Console.Clear();
                Console.WriteLine("Please Enter INrange Number.'nPress any Key to Continue....");
                Console.ReadKey();
                ShowStudent();
                break;
        }
        // Use variable 'students' here
        // Remember to check for null as it might not have been mutated in the switch-case.
        if (students != null)
        {
            // Do something with students here... just printing it for now.
            Console.WriteLine(students.ToString());
        }
    }
    public static Students[] ReceiveStudent()
    {
        Console.Clear();
        int n;
        Console.WriteLine("How Many Student's you Want to Enter?");
        n = Convert.ToInt32(Console.ReadLine());
        Students[]  st = new Students[n];
        for (int i = 0; i < n; i++)
        {
            Console.WriteLine("Enter Student ID:");
            st[i].ID = Convert.ToInt32(Console.ReadLine());
            Console.WriteLine("Enter Student CODE:");
            st[i].studentCode = Convert.ToInt32(Console.ReadLine());
            Console.WriteLine("Enter Student Name:");
            st[i].name = Console.ReadLine();
            Console.WriteLine("Enter Student Family:");
            st[i].family = Console.ReadLine();
            Console.WriteLine("Enter Student Major:");
            st[i].Major = Console.ReadLine();                         
        }
        ShowStudent();
        return st;
    }
}
