How Can I Efficiently Find the Object with the Maximum Property Value in a Collection?

Find an object with the maximum attribute value in the collection

Suppose you have a list of objects that contain multiple integer attributes (such as height and width). The goal is to identify and retrieve objects with the highest height attribute value. Although the maximum height value can be determined, retrieval may be challenging.

One method is to use MAXBY extensions in the morelinq library. This method iterates collection, tracking the maximum value and associated object. The grammar is as follows:

This method has the following advantages:

<code>DimensionPair item = items.MaxBy(x => x.Height);</code>

Efficient execution:

Its time complexity is O (n), unlike other methods that repeatedly search for maximum values ​​(cause O (n^2) complexity).
  • Simple implementation: The simplicity makes it easy to understand and achieve.
  • Single iteration:
  • Each element is evaluated only once projection, so as to maximize performance.
  • By using the Maxby extension method, you can effectively find objects with the maximum high attribute value in the collection.
