What is faster in finding element with property of maximum value

Question

Commonly, to find element with property of max value I do like this

var itemWithMaxPropValue = collection.OrderByDescending(x => x.Property).First();
         


        

Answer 1

I will go with Max since it is specifically designed for that purpose. Sorting to find Max value seems to be too much.

Also, I wouldn't use Where for finding the max, but Single - since what we need here is but a Single value.

var maxValOfProperty = collection.Max(x => x.Property);
var itemWithMaxPropValue = collection
                            .Single(x => x.Property == maxValueOfProperty);

Or alternatively using First (if the collection contains duplicates of max value)

var maxValOfProperty = collection.Max(x => x.Property);
var itemWithMaxPropValue = collection
                            .First(x => x.Property == maxValueOfProperty);

Or, using MoreLINQ (as suggested by Kathi), you could do it with MaxBy:

var itemWithMaxPropValue = collection.MaxBy(x => x.Property);
