Question

我遇到方法问题。因此，在一个方法中，我向用户询问名字，我想将该String存储在另一个方法中，然后让我的main方法调用存储String的方法。但我在存储该字符串时遇到了麻烦。我使用此代码：

static void GetStudentInformation()
{
    Console.WriteLine("Enter the student's first name: ");
    string firstName = Console.ReadLine();
}

static void PrintStudentDetails(string first)
{
    Console.WriteLine("{0}", first);
}

public static void Main (string[] args){
    GetStudentInformation();
}

因此，一旦输入名称，它应该存储在详细信息方法中，然后在main方法中调用。谢谢你提前帮助我。

Answer 1

static string GetStudentInformation()
{
     Console.WriteLine("Enter the student's first name: ");
     return Console.ReadLine();
}

static void PrintStudentDetails(string first)
{
     Console.WriteLine("{0}", first);
}

public static void Main (string[] args)
{
     string firstName = GetStudentInformation();
     PrintStudentDetails(firstName);
}

如果您需要从用户检索多个输入。您可以返回字符串列表（快速解决方案）：

static List<string> GetStudentInformation()
    {
         List<string> studentInformation = new List<string>();

         //first name
         Console.WriteLine("Enter the student's first name: "));
         studentInformation.Add(Console.ReadLine());

         //last name
         Console.WriteLine("Enter the student's last name: "));
         studentInformation.Add(Console.ReadLine());

         //more
         return studentInformation;
    }

    static void PrintStudentDetails(List<string> studentInformation)
    {
         foreach (string info in studentInformation)
         {
              Console.WriteLine("{0}", info);
         }
    }

    public static void Main (string[] args)
    {
         List<string> studentInformation = GetStudentInformation();
         PrintStudentDetails(studentInformation);
    }

或创建一个类来存储所有输入（更好的解决方案）：

 class Student
    {
        public string FirstName {get;set;}
        public string LastName {get;set;}
    }

static Student GetStudentInformation()
    {
         Student student = new Student();

         //first name
         Console.WriteLine("Enter the student's first name: "));
         student.FirstName = Console.ReadLine();

         //last name
         Console.WriteLine("Enter the student's last name: "));
         student.LastName = Console.ReadLine();

         //more
         return student;
    }

    static void PrintStudentDetails(Student student)
    {
        Console.WriteLine("{0}", student.FirstName);
        Console.WriteLine("{0}", student.LastName);
    }

    public static void Main (string[] args)
    {
         Student student = GetStudentInformation();
         PrintStudentDetails(student);
    }

Answer 2

Student.java

public class Student {

    private String studentName;

    public Student(String studentName) {
        this.name = studentName;
    }

    public static String getStudentName() {
        return studentName;
    }
    public static void setStudentName(String newName) {
        studentName = newName;
    }

然后你可以这样做：

Student aStudent = new Student(Console.ReadLine);

我知道这对于您的特定情况并不完全有效，但它只是为了显示您想要做的事情背后的基本逻辑。

用户输入存储在方法中
