在.NET通用词典更改订单 [英] Changing the Order in a .NET Generic Dictionary

问题描述

我有一个从一个普通的字典继承了如下一类：

  MyClass类：System.Collections.Generic.Dictionary< ; INT，对象> 
  

我在一个特定的顺序添加值的列表，但我现在希望改变这种状况订购。有什么办法（无需拆卸和重新添加），我可以有效地重新索引值;因此在指数1更改对象现在处于例如指数10？例如，这不起作用：

  MyClass的[1]的.index = 10; 
  

解决方案

本身字典没有索引顺序。可考虑从 KeyedCollection 类继承来代替。它是一个字典和一个普通的列表的合并，它的设计使用的项目，如钥匙的一员，并有一个索引顺序

I have a class that inherits from a generic dictionary as follows:

Class myClass : System.Collections.Generic.Dictionary<int, Object>

I have added a list of values to this in a particular order, but I now wish to change that order. Is there any way (without removing and re-adding) that I could effectively re-index the values; so change the object at index 1 to now be at index 10 for example? For example, this doesn't work:

myClass[1].Index = 10;

解决方案

Dictionaries by themselves don't have an index order. Consider inheriting from the KeyedCollection class instead. It's a merge of a dictionary and an ordinary list, and it's designed to use a member of your items as the key, and have an index order.
