Max, MinIn C# programs we call Max (and Min) from System.Linq to get the largest or smallest element. Each element is iterated in the search.
These methods can also be used with lambda expressions. Higher-order functions can make programs shorter (but sometimes slower and harder to read).
MaxTo begin, we must include System.Linq for this program to compile. Max() is an extension method (found in the Linq namespace).
Max method is called upon this array. Max returns 1 because 1 is the largest value in the program's array.Max with a lambda expression. The value 2 is returned—the absolute value of -2 is 2, and 2 is the maximum.using System;
using System.Linq;
// Step 1: create array.
int[] array1 = { 1, -1, -2, 0 };
// Step 2: use simple Max to find maximum number.
Console.WriteLine(array1.Max());
// Step 3: find maximum number when all numbers are made positive.
Console.WriteLine(array1.Max(element => Math.Abs(element)));1
2MinWe want to find the minimum value in a collection (such as an array or List) in a simple way. With Min() we find the minimum element or the minimum value after a transformation.
Min() method determines that -1 is the smallest integer.Min() provides a clear way to find the smallest value in a collection.using System;
using System.Linq;
int[] array1 = { 1, -1, 2, 0 };
// Part 1: find minimum number.
Console.WriteLine(array1.Min());
// Part 2: find minimum number when all numbers are made negative.
Console.WriteLine(array1.Min(element => -element));-1
-2Math.MaxThe Math class contains some math methods like Max and Min that also find the lower or higher number. But these are simpler and only test 2 numbers.
The Max function can find either the maximum value in a collection, or the maximum value after a specific transformation is applied. Min returns the minimum value.
These methods are perhaps most useful with a lambda expression: this makes the computation adjustable. Other forms of delegates (not just lambdas) can be used.
