最佳实现键值对数据结构？

所以我最近一直在用C＃，所有的通用集合我有点困惑。说我想表示一个数据结构，其中树的头是一个键值对，然后有一个键值对的可选列表下面（但没有更多的级别）。这是合适的吗？

So I've been poking around with C# a bit lately, and all the Generic Collections have me a little confused. Say I wanted to represent a data structure where the head of a tree was a key value pair, and then there is one optional list of key value pairs below that (but no more levels than these). Would this be suitable?

public class TokenTree { public TokenTree() { /* I must admit to not fully understanding this, * I got it from msdn. As far as I can tell, IDictionary is an * interface, and Dictionary is the default implementation of * that interface, right? */ SubPairs = new Dictionary<string, string>(); } public string Key; public string Value; public IDictionary<string, string> SubPairs; }

这真的是一个简单的分流传递数据。

It's only really a simple shunt for passing around data.

推荐答案

有一个实际的数据类型叫做KeyValuePair，使用像这样

There is an actual Data Type called KeyValuePair, use like this

KeyValuePair<string, string> myKeyValuePair = new KeyValuePair<string,string>("defaultkey", "defaultvalue");
