.NET 中有字典的替代品吗？
我需要在项目中使用字典，但我们知道它们只能使用键访问，不能使用索引，并且我想使用索引访问字典中的项目。因此，我在网上闲逛，发现了 OrderedDictionary，因为它们可以使用索引和键访问，但它们有一些 性能问题 而且我每天每分钟都在读/写字典，所以使用 OrderedDictionary 不是一个好主意。
所以最后我的问题是，是否有任何可用的替代方案可以为我提供字典的功能，并且我还可以使用索引访问它并且不会导致性能问题。
I have a requirement of using a dictionary in the project but as we know that they are only accessible using the keys and not using the indexes, and I want to access the items in dictionary using indexes. So I fiddle over the web and found out about OrderedDictionary as they are accessible using both the indexes and keys but they have some performance issue and as I am reading/writing the dictionary every minute of the day so it's not a good idea to use OrderedDictionary.
So lastly my question in here is that is there any alternative available which gives me functionality of Dictionary and I can also access it using indexes and doesn't cause a performance issue.

SortedList有一个属性Values，即IList。够了吗？仅对于小“组”元素来说它才快。与SortedDictionary的区别在于 http://msdn.microsoft.com/en-us/library/5z658b67(v=vs.80).aspx我可以问你为什么要访问它吗“按索引”？你仍然可以用 foreach 枚举它，你知道吗？
SortedList<TKey, TValue>has a property,Values, that is anIList<TValue>. Is it enough? It's fast only for small "sets" of elements. The difference withSortedDictionaryis here http://msdn.microsoft.com/en-us/library/5z658b67(v=vs.80).aspxCan I ask you why you want to access it "by index"? You can still enumerate it with foreach, you know?
为了回应您的评论，您只期望每分钟一百次更新，这是很少的工作 - 几乎没有什么。您仍然可以使用
OrderedDictionary，性能对您来说不是问题。in response to your comment that you are only expecting a hundred updates a minute, this is very little work - practically nothing. You can still use an
OrderedDictionary, performance will not be an issue for you.尝试排序字典
