En LINQ, puede encontrar la suma de los elementos numéricos dados mediante el método Sum() . Este método calcula la suma del valor numérico presente en la secuencia dada. No es compatible con la sintaxis de consulta en C#, pero es compatible con VB.NET . Está disponible en las clases Enumerable y Queryable en C#. Puede funcionar con valores decimales anulables, no anulables, dobles, flotantes, int, etc.
Ejemplo 1:
// C# program to illustrate how to
// find the sum of the given sequence
using System;
using System.Linq;
class GFG {
// Main Method
static public void Main()
{
int[] sequence = { 20, 30, 50, 78, 90,
79, 89, 99, 97, 29 };
// Display the sequence
Console.WriteLine("The Sequence is: ");
foreach(int s in sequence)
{
Console.WriteLine(s);
}
// Finding sum of the given sequence
// Using Sum function
int result = sequence.Sum();
Console.WriteLine("The sum of the given "
+ "sequence is: {0}",
result);
}
}
Producción:
The Sequence is: 20 30 50 78 90 79 89 99 97 29 The sum of the given sequence is: 661
Ejemplo 2:
// C# program to find the sum
// of the salary of the employee
using System;
using System.Linq;
using System.Collections.Generic;
// Employee details
public class employee {
public int emp_id
{
get;
set;
}
public string emp_name
{
get;
set;
}
public string emp_gender
{
get;
set;
}
public string emp_hire_date
{
get;
set;
}
public int emp_salary
{
get;
set;
}
}
class GFG {
// Main method
static public void Main()
{
List<employee> emp = new List<employee>() {
new employee() { emp_id = 209, emp_name = "Anjita", emp_gender = "Female", emp_hire_date = "12/3/2017", emp_salary = 20000 },
new employee() { emp_id = 210, emp_name = "Soniya", emp_gender = "Female", emp_hire_date = "22/4/2018", emp_salary = 30000 },
new employee() { emp_id = 211, emp_name = "Rohit", emp_gender = "Male", emp_hire_date = "3/5/2016", emp_salary = 40000 },
new employee() { emp_id = 212, emp_name = "Supriya", emp_gender = "Female", emp_hire_date = "4/8/2017", emp_salary = 40000 },
new employee() { emp_id = 213, emp_name = "Anil", emp_gender = "Male", emp_hire_date = "12/1/2016", emp_salary = 40000 },
new employee() { emp_id = 214, emp_name = "Anju", emp_gender = "Female", emp_hire_date = "17/6/2015", emp_salary = 50000 },
};
// Find the sum of the salary
// Using Sum () method
var res = emp.Sum(a = > a.emp_salary);
Console.WriteLine("Total salary of the Employees: {0}", res);
}
}
Producción:
Total salary of the Employees: 220000
