How to Find the Object with the Maximum Property Value Using LINQ?

The object with the maximum attribute value in the linq search set

Linq provides a convenient way to find objects with the maximum attribute value in the set. Let's take a look at an example:

Assuming we have a list of

objects, each object has

and DimensionPair attributes: Height Width

We need to find and return the object with the largest attribute value.

<code class="language-csharp">public class DimensionPair
{
    public int Height { get; set; }
    public int Width { get; set; }
}</code>

We can use the method to easily achieve: Height

Through Lambda expression MaxBy(), we told linq to compare the

attributes of each object and select the object with the maximum value. The result is assigned to variables.

<code class="language-csharp">var maxItem = items.MaxBy(x => x.Height);</code>

This method has the following advantages: x => x.Height Height maxItem Efficiency:

Different methods that calculate the maximum value in each iteration before,

only need to traverse the collection once, and the time complexity is O (n).

Simple grammar:
• The grammar is clear and simple, easy to understand and achieve. Flexibility: MaxBy()
It can be applied to any collection to find objects with the largest attribute value.
