How to get the maximum of more than 2 numbers in Visual C#?

Question

I have an array of five numbers and an array of 2 numbers. How would I find out the largest number among these 7 numbers? Is there a method that can make things easier?

Answer 1

If you're using 3.5 you could use Linq:

using System.Linq;
var values = new int[] { 1,2,3,4,5 };
var maxValue = values.Max();

Answer 2

int[] array1 = { 0, 1, 5, 2, 8 };
int[] array2 = { 9, 4 };

int max = array1.Concat(array2).Max();
// max == 9

Answer 3

Straightforward way:

Math.Max(Math.Max(a,b), c)//on and on for the number of numbers you have

using LINQ:

int[] arr1;
int[] arr2;
int highest = (from number in new List<int>(arr1).AddRange(arr2)
               orderby number descending
               select number).First();

Answer 4

You can try

decimal max = Math.Max(arr1.Max(), arr2.Max());
