int[] myArray = { 1, 2, 3, 4, 5 }; int sum = System.Linq.Enumerable.Sum(myArray); Console.WriteLine(sum); // Output: 15
ListThis code uses the same System.Linq package library, but operates on a List of doubles. The Sum method is called on the Enumerable class, which takes a list as input and returns the sum of its values. In this example, the output is 17.5. In conclusion, System Sum is a package library in C# that allows for calculating the sum of values in an array or list. It can be used in various mathematical and statistical applications.myList = new List { 1.5, 2.5, 3.5, 4.5, 5.5 }; double sum = System.Linq.Enumerable.Sum(myList); Console.WriteLine(sum); // Output: 17.5
