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

Little extension method:

public static KeyValuePair GetMaxValuePair(this Dictionary source)
    where V : IComparable
{
    KeyValuePair maxPair = source.First();
    foreach (KeyValuePair pair in source)
    {
        if (pair.Value.CompareTo(maxPair.Value) > 0)
            maxPair = pair;
    }
    return maxPair;
}

Then:

int keyOfMax = myDictionary.GetMaxValuePair().Key;
