索引器的目的是什么? [英] What the purpose of Indexers?

问题描述

不了解索引器的目的.示例:

Not understand the purpose of Indexers. Example:

class MyCls
{
   object[] myArr = new object[];
   public object this[int i]
   {
      get{return myArr[i];}
      set{myArr[i] = value;}
   }
}

为什么不只为myArr创建一个属性并通过它的属性访问它呢?

Why not just create a property for myArr and access it through it''s property?
What''s the advantage and/or purpose of using an Indexer?

推荐答案

对！为什么不只创建具有唯一名称的属性?没有关于此功能的原则.

Right! Why not just create a property with the distinct name? There is nothing principal about this feature.

这仅是语法糖，请参见 http://en.wikipedia.org/wiki/Syntactic_sugar [ ^ ].

This is nothing more than the syntactic sugar, see http://en.wikipedia.org/wiki/Syntactic_sugar[^].

作为语法糖，这是非常好的糖，它遵循其他语言的传统.

Being the syntactic sugar, this is very nice sugar, following nice tradition from other languages.
