//C# program to get the size of a specified folder 
//including sub-folder.

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

class Demo
{
    static long GetSizeOfFolder(DirectoryInfo dInfo, bool isSubFolder)
    {
        long sizeInBytes = dInfo.EnumerateFiles().Sum(file => file.Length);

        if (isSubFolder == true)
            sizeInBytes += dInfo.EnumerateDirectories().Sum(dir => GetSizeOfFolder(dir, true));

        return sizeInBytes;
    }

    static void Main(string[] args)
    {
        long sizeOfDir;
        double sizeGb;

        DirectoryInfo dInfo = new DirectoryInfo(@"D:/movie");
        sizeOfDir = GetSizeOfFolder(dInfo, true);
        sizeGb = ((double)sizeOfDir) / (1024*1024*1024);

        Console.WriteLine("Size of folder including sub-folder in GB: "+sizeGb);
    }
}

Output:

Size of folder including sub-folder in GB: 14.6635034512728

Explanation:

Here, we created a class Demo that contains two static methods GetSizeOfFolder() and Main(). Here we get the size of the specified folder including the sub-folder using DirectoryInfo class with LINQ Sum() and EnumerateFiles() methods. It returns the size of the folder in bytes then we converted the number of bytes into gigabytes by dividing by (1024*1024*1024), then print size into gigabytes on the console screen.
