C＃关联数组 [英] C# associative array

问题描述

我一直在使用Hashtable，但从本质上来说，哈希表不是有序的，我需要保持一切顺序，因为我添加他们（因为我想把它们以相同的顺序）。例如如果我这样做：

I've been using a Hashtable, but by nature, hashtables are not ordered, and I need to keep everything in order as I add them (because I want to pull them out in the same order). Forexample if I do:

pages["date"] = new FreeDateControl("Date:", false, true, false);
pages["plaintiff"] = new FreeTextboxControl("Primary Plaintiff:", true, true, false);
pages["loaned"] = new FreeTextboxControl("Amount Loaned:", true, true, false);
pages["witness"] = new FreeTextboxControl("EKFG Witness:", true, true, false);

当我做一个foreach时，我想能够按顺序得到它：

And when I do a foreach I want to be able to get it in the order of:

pages["date"]  
pages["plaintiff"]  
pages["loaned"]  
pages["witness"] 

我如何做？

推荐答案

我相信.NET有 OrderedDictionary 类来处理这个。它不是通用的，但它可以作为一个体面的Hashtable替代 - 如果你不关心严格的类型安全。

I believe that .NET has the OrderedDictionary class to deal with this. It is not generic, but it can serve as a decent Hashtable substitute - if you don't care about strict type safety.

我写了一个通用的包装器类，我愿意分享。

I've written a generic wrapper around this class, which I would be willing to share.
