How do I use the Average function in C# LINQ?

The Average function in C# LINQ is used to calculate the average of a sequence of numeric values. You can use it like this: var average = numbers.Average(); where numbers is your collection.

Can you show me a complete example?

Sure! Here's a complete example:

using System;
using System.Collections.Generic;
using System.Linq;

class Program
{
    static void Main()
    {
        List<int> numbers = new List<int> { 1, 2, 3, 4, 5 };
        double average = numbers.Average();
        Console.WriteLine("Average: " + average);
    }
}

This will output: Average: 3.

What if I have a list of objects instead of numbers?

You can use a lambda expression to specify the property you want to average. For example:

class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
}

List<Person> people = new List<Person>
{
    new Person { Name = "Alice", Age = 30 },
    new Person { Name = "Bob", Age = 40 }
};

double averageAge = people.Average(p => p.Age);
Console.WriteLine("Average Age: " + averageAge);

This will output: Average Age: 35.
