如何删除数据

Question

好吧，所以我有一个c＃简单程序，您可以输入您的姓名，姓氏和年龄，所以我试图找到一种方法，在程序运行时可以从程序中删除特定数据。例如，我输入一个名称和一个姓氏，然后获得一个删除该名称或姓氏的选项。

下面列出了代码！

using System;

namespace calc
{


public class Student
{
   public string firstName;
    public string lastName;
    public int age;
}





class MainClass
{

    public static void Main(string[] args)
    {

        Console.WriteLine("Choose from one of the following");

        Console.WriteLine(" 1. Add Student ");
        Console.WriteLine(" 2. Remove Student ");

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

        string[] names = new string[4];

        if (number == 1)
        {

            // code for adding student name and storing it in an array


                Console.WriteLine("Write Student first name");
                Student first1 = new Student();
                string first = Console.ReadLine();
                first1.firstName = first;


            // takes in students last name

            Console.WriteLine(" Write Student Last Name");
            Student last1 = new Student();
            string last = Console.ReadLine();
            last1.lastName = last;


            // takes age
            Console.WriteLine(" Write age");

            Student age1 = new Student();
            int age = int.Parse(Console.ReadLine());
            age1.age = age;


            Console.WriteLine(first1.firstName);
            Console.WriteLine(last1.lastName);
            Console.WriteLine(age1.age);
        }

        else if (number == 2)
        {

            Console.WriteLine(" 1. Remove First Name ");
            Console.WriteLine(" 2. Remove Last Name ");

            int number2 = int.Parse(Console.ReadLine());


            if (number2 == 1)
            { 
            }

        }




    }

}
