定义一个员工的集合，对员工集合内的元素进行查询和删除。
实现员工的签到和签退，要求如下：
//A：每天只能签到一次
//B：签退前必须已经签到
//C：显示打卡记录
代码如下：
员工信息类：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks; namespace StringTest
{
class Employee
{ private int id; public int ID
{
get { return id; }
set { id = value; }
}
private string name; public string Name
{
get { return name; }
set { name = value; }
}
private string sex; public string Sex
{
get { return sex; }
set { sex = value; }
}
private int age; public int Age
{
get { return age; }
set { age = value; }
} // A：实现新增员工（工号，年龄，姓名，性别） public Employee(int _id, int _age, string _name, string _sex)
{
this.Name = _name;
this.Age = _age;
this.Sex = _sex;
this.ID = _id;
} //B：展示员工信息， public void ShowMsg()
{ Console.WriteLine("工号：{0} 年龄：{1} 姓名：{2} 性别：{3}", this.ID, this.Age, this.Name, this.Sex);
}
}
}
公司信息类
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks; namespace StringTest
{
class Company
{
public List<Employee> list = new List<Employee>();
public Dictionary<string, List<KaoqinRecord>> dicKaoQinEachDay = new Dictionary<string, List<KaoqinRecord>>();
public void AddEmp(Employee sc)
{
list.Add(sc);
} public void DelEmp(int nID)
{
for (int i = ; i < list.Count; i++)
{
if (list[i].ID == nID)
{
list.RemoveAt(i);
}
}
} public void PrintAllEmp()
{
for (int i = ; i < list.Count; i++)
{
list[i].ShowMsg();
} } public Employee FindEmp(int nID)
{

{

{
return list[i];
}
}
return null;
}
}
}
考勤记录类
