C# 实现学生管理系统

学生管理系统的实现可以使用C#语言。下面是一个简单的示例代码，实现了学生信息的录入、显示和搜索功能：

using System;
using System.Collections.Generic;

class Student
{
    public string Name { get; set; }
    public int Age { get; set; }
    public string Department { get; set; }
}

class StudentManagementSystem
{
    private List<Student> students = new List<Student>();

    public void AddStudent()
    {
        Console.WriteLine("请输入学生姓名：");
        string name = Console.ReadLine();

        Console.WriteLine("请输入学生年龄：");
        int age = int.Parse(Console.ReadLine());

        Console.WriteLine("请输入学生所在系别：");
        string department = Console.ReadLine();

        Student student = new Student
        {
            Name = name,
            Age = age,
            Department = department
        };

        students.Add(student);
        Console.WriteLine("学生信息添加成功！");
    }

    public void DisplayStudents()
    {
        Console.WriteLine("学生信息列表：");
        foreach (var student in students)
        {
            Console.WriteLine($"姓名：{student.Name}，年龄：{student.Age}，系别：{student.Department}");
        }
    }

    public void SearchStudent()
    {
        Console.WriteLine("请输入要搜索的学生姓名：");
        string searchName = Console.ReadLine();

        bool found = false;
        foreach (var student in students)
        {
            if (student.Name == searchName)
            {
                Console.WriteLine($"姓名：{student.Name}，年龄：{student.Age}，系别：{student.Department}");
                found = true;
                break;
            }
        }

        if (!found)
        {
            Console.WriteLine("未找到该学生信息！");
        }
    }
}

class Program
{
    static void Main(string[] args)
    {
        StudentManagementSystem sms = new StudentManagementSystem();

        while (true)
        {
            Console.WriteLine("请选择操作：");
            Console.WriteLine("1. 添加学生信息");
            Console.WriteLine("2. 显示学生信息");
            Console.WriteLine("3. 搜索学生信息");
            Console.WriteLine("4. 退出");

            int choice = int.Parse(Console.ReadLine());

            switch (choice)
            {
                case 1:
                    sms.AddStudent();
                    break;
                case 2:
                    sms.DisplayStudents();
                    break;
                case 3:
                    sms.SearchStudent();
                    break;
                case 4:
                    return;
                default:
                    Console.WriteLine("无效的选项！");
                    break;
            }
        }
    }
}

这段代码实现了一个简单的学生管理系统，可以通过控制台交互来录入学生信息、显示学生信息和搜索学生信息。你可以根据实际需求进行修改和扩展。
