C#: Calculate the size of file

C# Sharp LINQ : Exercise-16 with Solution

Write a program in C# Sharp to calculate size of file using LINQ

Sample Solution:

C# Sharp Code:

using System;
using System.Linq;
using System.IO;

// Define a class named LinqExercise16
class LinqExercise16
{
    // Main method, the entry point of the program
    static void Main(string[] args)
    {
        // Get an array of file names present in the directory "/home/w3r/abcd/"
        string[] dirfiles = Directory.GetFiles("/home/w3r/abcd/");
        // Note: There are three files in the directory "abcd" named abcd.txt, simple_file.txt, and xyz.txt

        // Display information about the program
        Console.Write("\nLINQ : Calculate the size of file : ");
        Console.Write("\n------------------------------------\n");

        // Calculate the average file size using LINQ
        var avgFsize = dirfiles.Select(file => new FileInfo(file).Length).Average();
        // Convert the average file size from bytes to megabytes and round to one decimal place
        avgFsize = Math.Round(avgFsize / 10, 1);
        // Display the average file size in megabytes
        Console.WriteLine("The Average file size is {0} MB", avgFsize);
        Console.ReadLine(); // Wait for user input before closing the program
    }
}

Sample Output:

The Average file size is 3.4 MB
