Good way to get the key of the highest value of a Dictionary in C#

Question

I\'m trying to get the key of the maximum value in the Dictionary results.

This is what I have so far:

double max          


        

Answer 1

This is a fast method. It is O(n), which is optimal. The only problem I see is that it iterates over the dictionary twice instead of just once.

You can do it iterating over the dictionary once by using MaxBy from morelinq.

results.MaxBy(kvp => kvp.Value).Key;
