c#OOP中包含对象的数组

Question

我遇到了一些代码的问题,它覆盖了已声明的先前对象的名称.

我看不出修复.我试图多次修复它,我的同学找不到修复,我的老师也找不到.

namespace OOP
{
    class Student
    {
        private static string name;
        private static DateTime DOB;
        private static int ID;
        private static double height;
        private static string tutor;

        public Student()
        {
            Console.Clear();
            //Console.WriteLine("This is for student: " + (count + 1));
            Console.WriteLine("Please enter the student's name");
            name = Console.ReadLine();


            //tryagain:
            //try
            //{
            //    Console.WriteLine("Please enter the Date of Birth");
            //    DOB = DateTime.Parse(Console.ReadLine());
            //    DOB = DOB.Date;
            //}
            //catch
            //{
            //    Console.WriteLine("Please enter a valid date format");
            //    goto tryagain;
            //} 

            //Console.WriteLine("Please enter the Student's ID");
            //ID = int.Parse(Console.ReadLine());

            //Console.WriteLine("Please enter the Student's Tutor");
            //tutor = Console.ReadLine().ToUpper();

            //Console.WriteLine("Please enter the Student's height(cm)");
            //height = double.Parse(Console.ReadLine());
        }
        public void DispayData()
        {            
            Console.WriteLine("Name- " + name);
            Console.WriteLine("Date of Birth- " + DOB.Date);
            Console.WriteLine("ID- " + ID);
            Console.WriteLine("Tutor- " + tutor);
            Console.WriteLine("Height- " + height);
        }
    }
    class Program
    {
        static void Main(string[] args)
        {            
            Console.WriteLine("Please enter the number of students");
            int numStuds = int.Parse(Console.ReadLine());
            Student[] studs = new Student[numStuds];
            for (int i = 0; i < numStuds; i++)
            {
                studs[i] = new Student();            
            }
            Console.Clear();
            for (int f = 0; f < numStuds; f++)
            {
                display(studs[f]);
            }
            Console.ReadKey();
        }

        static void display(Student stud)
        {
            stud.DispayData();
            Console.WriteLine();
        }
    }    
}

Answer 1

问题是Student类的字段是静态的,因此在该类的所有实例之间共享.所以只需删除即可static.
