获取字典中的最大关键 [英] Get the largest key in a dictionary

问题描述

我有那些按键整数字典。我想获得最大的关键。我不跟踪钥匙所以他们可能是连续的（如1,2,3,4,5,6），但可能会跳过（1,3,4,5），但我怀疑有什么差别。

I have a dictionary with keys that are ints. I would like to get the largest key. I don't keep track of keys so they might be consecutive (e.g. 1,2,3,4,5,6) but might skip (1,3,4,5) although I doubt that makes any difference.

我只是用二进制搜索还是有方法？至于我看到你很难击败的二进制搜索这样一个简单的任务 - 也许你可以减少一半。

Do I just use a binary search or is there a method? As far as I see you can hardly beat binary search for such a simple task - maybe you can halve it.

推荐答案

如果你有LINQ提供，你应该能够做到：

If you have LINQ available, you should be able to do:

myDictionary.Keys.Max();
