c# - 如何创建一个数组来保存结构？

Question

我被要求创建一些结构:学生、教师、类(class)、项目 然后制作一个数组来保存 5 个学生结构，并为数组中学生的字段赋值，我一直在创建数组来保存结构，这里是代码:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Module4Assignment
{
    class Program
    {
        //Student structure: 
        public struct Student
        {
            public Student (string name , string address , string country , string birthday , int telephone)
            {
                this.Name = name;
                this.Address = address;
                this.Country = country;
                this.Birthday = birthday;
                this.Telephone =telephone;
            }

            public string Name;
            public string Address;
            public string Country;
            public string Birthday;
            public int Telephone;
        }

        //Teacher structure:
        public struct Teacher
        {
            public Teacher(string tname, string taddress, string tcountry, string tbirthday, int ttelephone)
            {
                this.TName = tname;
                this.TAddress = taddress;
                this.TCountry = tcountry;
                this.TBirthday = tbirthday;
                this.TTelephone = ttelephone;
            }

            public string TName;
            public string TAddress;
            public string TCountry;
            public string TBirthday;
            public int TTelephone;
        }

        //Program structure
        public struct Program
        {
            public Program(string pname , string department , int pcredits)
            {
                this.PName = pname;
                this.Department = department;
                this.PCredits = pcredits;

            }
            public string PName;
            public string Department;
            public int PCredits;
        }

        //Course structure
        public struct Course
        {
            public Course(string cname, string day, int ccredits)
            {
                this.CName = cname;
                this.Day = day;
                this.CCredits = ccredits;

            }
            public string CName;
            public string Day;
            public int CCredits;
        }


        static void Main(string[] args)
        {
            //Instantiating 5 students structures:
            Student student1 = new Student();
            Student student2 = new Student();
            Student student3 = new Student();
            Student student4 = new Student();
            Student student5 = new Student();


            //creating the array:
            string[] studentArray = new string[5];
            studentArray[0]=student1;
            studentArray[1]=student2;
            studentArray[2]=student3;
            studentArray[3]=student4;
            studentArray[4]=student5;
        }
    }
}

我对您在这里所做的事情有很多疑问，但简单的答案是您不能将 Student 对象放入字符串数组中:

static void Main(string[] args)
    {
        //Instantiating 5 students structures :
        Student student1 = new Student();
        Student student2 = new Student();
        Student student3 = new Student();
        Student student4 = new Student();
        Student student5 = new Student();


        //creating the array :
        Student [] studentArray = new Student[5]; // <---- array of Student!
        studentArray[0]=student1;
        studentArray[1]=student2;
        studentArray[2]=student3;
        studentArray[3]=student4;
        studentArray[4]=student5;
    }
