有谁能告诉我，如何在主体上实现我的功能？所有的工作，但我想做一个雇主的目录，那么如何写雇主名单或大量？
class Catalog : Employe
{
Employe[] employes = new Employe[10];
Employe p1 = new Employe(14, "Mark", "James", 124151, "Coder", 4000);
public Catalog(int _age, string _firstName, string _lastName, int _id, string _job, int _salary) : base(_age, _firstName, _lastName, _id, _job, _salary)
{
employes[1] = p1;
}
public void CatalogLog()
{
for(int i = 0; i < employes.Length; i++)
Console.WriteLine(employes[i]);
}
}
class TestInheritence
{
public static void Main(string[] args)
{
Employe[] employes = new Employe[10];
}

我认为您没有用正确的逻辑设置继承层次结构。基类Employee是可扩展的，包含基本方法：
public class Employee
{
private int _id;
private string _firstName;
public Employee(int id, string firstName)
{
_id = id;
_firstName = firstName;
}
public int GetID()
{
return _id;
}
public void SetID(int id)
{
if(id > 0)
_id = id;
}
public void Print()
{
Console.WriteLine("ID: {0}\tFirst Name: {1}", this._id, this._firstName);
}
}派生类允许通过向基类的属性添加新方法和属性来展开对象：
public class Manager : Employee
{
private string _city;
public Manager(int id, string firstName, string city) : base(id, firstName)
{
_city = city;
}
public string GetCity()
{
return _city;
}
}要测试这两个类的工作方式，可以查看下面的应用程序代码：
public class Program
{
public static void Main()
{
Employee[] employees = new[]
{
new Employee(1, "Thomas"),
new Employee(2, "John"),
new Employee(3, "Erick"),
new Employee(4, "Ahmet"),
new Employee(5, "Sun")
};
employees[0].Print();
Manager manager = new Manager(6, "Johnson", "London");
manager.Print();
Console.WriteLine("City: {0}", manager.GetCity());
}

如果要将员工添加到目录中，可以使用“添加”函数将雇员添加到目录中：
class Catalog : Employe
{
List<Employe> employes = new List<Employe>();
public void AddEmployee(int _age, string _firstName, string _lastName, int _id, string _job, int _salary) : base(_age, _firstName, _lastName, _id, _job, _salary)
{
Employe p1 = new Employe(_age, _firstName, _lastName, _id, _job, _salary);
employes.Add(p1);
}
public void CatalogLog()
{
for(int i = 0; i < employes.Count(); i++)
Console.WriteLine(employes[i]);
}
}
class TestInheritence
{
public static void Main(string[] args)
{
Catalog catalog = new Catalog();
catalog.AddEmployee(14, "Mark", "James", 124151, "Coder", 4000);
// Add more employees.
}
}但我认为这是继承的错误用例。通常，当类型之间存在“is -a”关系时，您希望继承。但是“目录”不是“雇员”的类型。
