使用List中的数组 - OOP - Generic List

Question

我创建了一个列表:

List<Employee> employees = new List<Employee();

我想实现这个目标:

Employee e1 = new Employee(Job.Employee, "Name", "C Sharp", "Oracle", "SQL");

我目前有这个:

Employee e1 = new Employee(Job.Employee, "Name", Skills.CSharp);

这是Employee类中的代码

public enum Job { Employee, Supervisor, Administrator };
public enum Skills {CSharp, SQL, PHP, Javascript, Web, Python, Oracle, CPlus, Perl };

protected Job job;
protected String employeeName;
protected String employeeName;

public Job Job
{
    get { return job; }
    protected set { job = value; }
}

public String EmployeeName
{
    get { return employeeName; }
    protected set { employeeName = value; }
}

public Skills Skills
{
    get {return skills; } 
}

我希望能够输入尽可能多的"技能",因为我使用了枚举,因此只能在员工e1中输入一项技能.

我如何在列表/构造函数中放入一系列"技能"？

您可以使用params数组参数将可变数量的Skills参数传递给构造函数:

public Employee(Job job, string name, params Skills[] skills)

您还必须修改skills字段以保存集合Skills而不是单个集合.如果您在创建员工后不添加/删除技能,或者IList<Skills>您需要修改集合,则可以将其设为数组.

例如:

public class Employee
{
    private List<Skills> _skills;       // skills stored as a private List 
                                        // to allow modification inside Employee class

    public Employee(Job job, string name, params Skills[] skills)
    {
        _skills = new List<Skills>(skills);
        ...
    }

    public IReadOnlyList<Skills> Skills // publicly visible as a read-only list
    {
        get { return _skills.AsReadOnly(); }
    }

    ...
}
