C＃，使用变量作为新对象的名称 [英] C#, using variable for name of new object

问题描述

using System;
using System.Collections.Generic;
using System.Text;

namespace ConsoleApp1
{
    public class Student
    {

        public static int Count = 0;

        public int ID   { get; set; }
        public string Name { get; set; }

        Dictionary<int, Student> students = new Dictionary<int, Student>();

        public Student (string name, int id)
        {
            Name = name;
            ID = id;
        }

        public static void addStudent()
        {

            Student.Count++; // incrementing value for new student id.

            Console.Write("Please enter student's name: "); // grabbing input from user.
            string studentName = Console.ReadLine();

            Console.WriteLine("Student ID value: {0}", Student.Count); // for testing.
            int studentID = Student.Count;

             /* Student (studentName) = new Student (studentName, studentID) -- The issue is with this line*/
             Student added = new Student(studentName, studentID) // using this as a temp for now.
             {
                Name = studentName,
                ID = studentID
             };

        
        }


    }
}

我尝试过的事情：



我觉得我已经尝试了一切。



我想使用变量的原因是因为学生将从Main的菜单中添加。



使用静态变量Count（在此类中）作为对象名称可能更有意义。



无论我还是需要使用变量。



非常感谢任何帮助。

What I have tried:

I feel like I've tried everything.

The reason I want to use a variable is because students will be getting added from a menu in Main.

It would probably make more sense to use the static variable Count (in this class) for the name of the object.

Regardless I would still need to use a variable.

Any help is greatly appreciated.

推荐答案

我不知道你在说什么，变量？您似乎已经使用一个来设置新Student对象的Name属性，但我不确定。当你说对象的名字时，我并不完全确定你指的是什么。



我认为你是什么寻找的是：

I have no idea what you're talking about, "variable"? It appears you're already using one to set the Name property of a new Student object, but I'm not sure. I'm not entirely sure what you're referring to when you say "name of object".

I think what you're looking for is this:

Student added = new Student(studentName, studentID);

或

or

Student added = new Student()
{
    Name = studentName,
    ID = studentID
};

我不明白为什么你需要一个变量...



如果您需要添加学生并根据学生姓名检索它，您可以使用字典。

i don't understand why you need a variable ...

if you need add student and retrieve it based on the student name you can do it with dictionary.

ictionary<string, int> dict = new Dictionary<string, int>();
dict.Add("student1", 1);
dict.Add("student2", 2);
dict.Add("student3", 3);
dict.Add("student4", 4);

并且可以根据关键

and can search students based on key

dict.ContainsKey("student1")

并根据键（学生姓名）提取值

and extract values based on the key (which is student name)

dict["student1"].ToString ());

i认为它可能对你有用...

i think it may work for you...
