集合作为属性的类与继承集合的类 [英] Classes with Collections as Properties vs. Classes Inheriting Collections

问题描述

最近我使用了一个类继承自一个集合，而不是在类中实例化的集合，这是可以接受的，还是会产生未知的问题进一步下来？以下示例为了清楚起见：

  public class Cars：List< aCar> 
  

而不是类似：

  public class Cars 
 {
 List< aCar> CarList = new List< aCar>（）;任何想法？

 
 h2_lin>解决方案
这个问题是你的Cars类仍然有从List继承的接口，这可能允许你不想要的操作。
 
Recently I used a class that inherits from a collection instead of having the collection instantiated within the class, is this acceptable or does it create unseen problems further down the road? Examples below for the sake of clarity:
public class Cars : List<aCar>
instead of something like:
public class Cars
{
 List<aCar> CarList = new List<aCar>();
}
Any thoughts?
解决方案
The problem with this is that your Cars class will still have the interface it inherits from List, which may allow operations you don't want.
