En LINQ, puede encontrar el promedio de la secuencia dada usando el método Promedio . Este método devuelve el promedio de los elementos presentes en la secuencia o colección dada. Devuelve valores anulables, decimales no anulables, dobles, flotantes, int, etc. 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#.
Ejemplo 1:
// C# program to find the average
// the given array
using System;
using System.Linq;
class GFG {
static public void Main()
{
// Data source
int[] sequence = { 20, 45, 50, 79, 90, 79, 89, 100, 567, 29 };
// Display the sequence
Console.WriteLine("The sequence is:");
foreach(int s in sequence)
{
Console.WriteLine(s);
}
// Finding the average of the element
// present in the given array
// Using Average function
double result = sequence.Average();
Console.WriteLine("Average is: {0}", result);
}
}
Producción:
The sequence is: 20 45 50 79 90 79 89 100 567 29 Average is: 114.8
Ejemplo 2:
// C# program to find the average
// salary of the employee
using System;
using System.Linq;
using System.Collections.Generic;
// Employee details
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;
}
}
public 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 average salary of the employee
// Using Average () method
var res = emp.Average(a => a.emp_salary);
Console.WriteLine("Average salary of the Employees: {0}", res);
}
}
Producción:
Average salary of the Employees: 36666.6666666667
