ขั้นแรก ตั้งค่าลำดับ
List<int> myList = new List<int> { 1, 2, 3, 4 ,5};
ค้นหาผลรวมโดยใช้เมธอด Queryable Sum()
myList.AsQueryable().Sum();
ตัวอย่าง
using System; using System.Linq; using System.Collections.Generic; public class Demo { public static void Main() { List<int> myList = new List<int> { 1, 2, 3, 4 ,5}; Console.WriteLine("Sum of elements in a list..."); foreach (int res in myList) { Console.WriteLine(res); } int sum = myList.AsQueryable().Sum(); Console.WriteLine("Sum = {0}", sum); } }
ผลลัพธ์
Sum of elements in a list... 1 2 3 4 5 Sum = 15
