c#数组与泛型列表 [英] c# array vs generic list

问题描述

我基本上想知道在下面提到的场景中使用通用列表而不是数组的区别或优势

i basically want to know the differences or advantages in using a generic list instead of an array in the below mentioned scenario

class Employee
{
    private string _empName;

    public string EmpName
    {
       get{ return _empName; }
       set{ _empName = value; }
    }
}

<小时>

1. Employee[] emp 
2. List<Employee> emp

谁能告诉我优点或缺点以及更喜欢哪一个?

can anyone please tell me the advantages or disadvantages and which one to prefer?

推荐答案

一个很大的区别是 List 可以扩展(可以调用 Add 就可以了)也可以收缩(可以调用删除它)而 Employee[] 的大小是固定的.因此，除非需要，Employee[] 很难使用.

One big difference is that List<Employee> can be expanded (you can call Add on it) or contracted (you can call Remove on it) whereas Employee[] is fixed in size. Thus, Employee[] is tougher to work with unless the need calls for it.
