C# / .NET - max value in an array

This article will show you how to find the maximum value in an array in C# / .NET.

Quick solution:

int[] array = new int[] { 1, 5, 2, 16, -5 };

int max = array.Max(); // from System.Linq
Console.WriteLine( max ); // 16

Practical examples

1. With Max() method from System.Linq.

using System;
using System.Linq;

public class Program
{
    public static void Main(string[] args) 
    {
        int[] array = new int[] { 1, 5, 2, 16, -5 };

        int max = array.Max();
        Console.WriteLine( max ); // 16
    }
}

2. By comparing all the elements in the array

using System;

public class Program
{
    static double Max(double[] array)
    {
        double result = Double.NegativeInfinity;
        foreach (double currentNumber in array)
        {
            if (result < currentNumber) result = currentNumber;
        }
        return result;
    }

    public static void Main(string[] args)
    {
        double[] numbersArray = new double[] { 1.4, 5.0, 2.2, 16.0, -5.0 };

        Console.WriteLine( Max( numbersArray ) ); // 16
    }
}
