尝试使用 C# 开发 HR 入职控制台应用程序

Question

我不太确定如何完成这个，因为这是我第一次尝试使用 C# 读写文本文件

我想用我的控制台应用程序做的是：

I) 从 HR 的文本文件中读取新员工记录列表，masterlist.txt。这 HRMasterlist.txt 文件包含新员工记录的完整详细信息。

II) 生成txt文件，存储不同部门所需的新员工记录列表。

每个部门需要的新员工信息不一样：

公司行政部门：全名、职务、部门

采购部门：称呼、全名、手机号、职务、部门

IT 部门：Nric、全名、开始日期、部门、手机号

这是我目前所做的：

Employee.cs

using System;
using System.ComponentModel.DataAnnotations;
using System.IO;
namespace SectionA
{
    public class Employee
    {
        public Employee(string nric, string fullname, string salutation, DateTime startdate, string designation, string department, string mobileno, string hiretype, double salary)
        {
            this.Nric = nric;
            this.FullName = fullname;
            this.Salutation = salutation;
            this.StartDate = startdate;
            this.Designation = designation;
            this.Department = department;
            this.MobileNo = mobileno;
            this.HireType = hiretype;
            this.Salary = salary;
            this.MonthlyPayout = 0.0;
        }
        public string Nric { get; set; }
        public string FullName { get; set; }
        public string Salutation { get; set; }
        [DataType(DataType.Date)]
        public DateTime StartDate { get; set; }
        public string Designation { get; set; }
        public string Department { get; set; }
        public string MobileNo { get; set; }
        public string HireType { get; set; }
        public double Salary {get; set;}
        public double MonthlyPayout {get; set;}
        
        public string forCorpAdmin(Employee that)
        {
            return //add code;
        }
        public string forProcurement()
        {
            return //add code;
        }

        public string forITDept()
        {
            return //add code;
        }

    }
}

Program.cs

using System;
using System.Collections.Generic;
using System.Globalization;
using System.IO;
namespace SectionA
{
    public delegate void GenerateTxtFile();
    public class Program
    {
       
        
        static void Main(string[] args)
        {
            List<Employee> emps= new List<Employee>()
            emps = readHRMasterList();
           
           generateInfoForCorpAdmin(emps);
           generateInfoForProcurement(emps);
           enerateInfoForITDepartment(emps)

           //when above can work, do delegate


        }

        public static List<Employee> readHRMasterList(List<Employee> emps)
        {
            string path = @"../HRMasterlist.txt";
           //add code to read the HRMasterlist.txt
           // use each row of data to create a employee object
            //store each object into the employee before you return to main()
            return emps;
        }

        public static void generateInfoForCorpAdmin(List<Employee> emps)
        {
            //• CorporateAdmin: FullName, Designation, Department
            //open a new file "CorporateAdmin.txt" and store the above format into the file
            //how to get the data frome the employee list pass in
                
        }
        public static void generateInfoForProcurement(List<Employee> emps)
        {
            //• Procurement: Salutation, FullName, MobileNo, Designation, Department
            //add code
        }

        public static void generateInfoForITDepartment()
        {
            //• ITDepartment: Nric, FullName, StartDate, Department, MobileNo
            //add code

        }

    }
}

最后，HRMasterList.txt
