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

Maybe this isn't a good use for LINQ. I see 2 full scans of the dictionary using the LINQ solution (1 to get the max, then another to find the kvp to return the string.

You could do it in 1 pass with an "old fashioned" foreach:

KeyValuePair max = new KeyValuePair(); 
foreach (var kvp in results)
{
  if (kvp.Value > max.Value)
    max = kvp;
}
return max.Key;
