àIn C# FAQs Series: We discuss most frequent questions asked on C# forums.

If you want to know about how many drives are connected to your computer. It’s very easy to detect using C#. Following is simple code…

Source Code:

using System;

using System.IO;

class MyProgram

{

public static void Main()

{

DriveInfo[] allDrives = DriveInfo.GetDrives();

foreach (DriveInfo d in allDrives)

{

Console.WriteLine("Drive {0}", d.Name);

Console.WriteLine(" File type: {0}", d.DriveType);

if (d.IsReady == true)

{

Console.WriteLine(" Volume label: {0}", d.VolumeLabel);

Console.WriteLine(" File system: {0}", d.DriveFormat);

Console.WriteLine(

" Available space to current user:{0, 15} bytes",

d.AvailableFreeSpace);

Console.WriteLine(

" Total available space: {0, 15} bytes",

d.TotalFreeSpace);

Console.WriteLine(

" Total size of drive: {0, 15} bytes ",

d.TotalSize);

}

}

}

}

Out-Put:

/*

This code produces output similar to the following:

Drive A:\

File type: Removable

Drive C:\

File type: Fixed

Volume label:

File system: FAT32

Available space to current user: 4770430976 bytes

Total available space: 4770430976 bytes

Total size of drive: 10731683840 bytes

Drive D:\

File type: Fixed

Volume label:

File system: NTFS

Available space to current user: 15114977280 bytes

Total available space: 15114977280 bytes

Total size of drive: 25958948864 bytes

Drive E:\

File type: CDRom

The actual output of this code will vary based on machine and the permissions

granted to the user executing it.
