Getting a list of logical drives

Question

How can I get the list of logial drives (C#) on a system as well as their capacity and free space?

Solution 1

System.IO.DriveInfo.GetDrives()

Solution 2

foreach (var drive in DriveInfo.GetDrives())
{
    double freeSpace = drive.TotalFreeSpace;
    double totalSpace = drive.TotalSize;
    double percentFree = (freeSpace / totalSpace) * 100;
    float num = (float)percentFree;

    Console.WriteLine("Drive:{0} With {1} % free", drive.Name, num);
    Console.WriteLine("Space Remaining:{0}", drive.AvailableFreeSpace);
    Console.WriteLine("Percent Free Space:{0}", percentFree);
    Console.WriteLine("Space used:{0}", drive.TotalSize);
    Console.WriteLine("Type: {0}", drive.DriveType);
}

Solution 3

Directory.GetLogicalDrives

Their example has more robust, but here's the crux of it

string[] drives = System.IO.Directory.GetLogicalDrives();

foreach (string str in drives) 
{
    System.Console.WriteLine(str);
}

You could also P/Invoke and call the win32 function (or use it if you're in unmanaged code).

That only gets a list of the drives however, for information about each one, you would want to use GetDrives as Chris Ballance demonstrates.

Solution 4

maybe this is what you want:

listBox1.Items.Clear();

foreach (DriveInfo f in DriveInfo.GetDrives())    
    listBox1.Items.Add(f);

Solution 5

You can retrieve this information with Windows Management Instrumentation (WMI)

 using System.Management;

    ManagementObjectSearcher mosDisks = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");
    // Loop through each object (disk) retrieved by WMI
    foreach (ManagementObject moDisk in mosDisks.Get())
    {
        // Add the HDD to the list (use the Model field as the item's caption)
        Console.WriteLine(moDisk["Model"].ToString());
    }

Theres more info here about the attribute you can poll

Is this something new that was added in the latest version of .NET. I wrote a small app to display this years ago but had to go the WMI route at the time. Very handy to know anyway... cheers

Quick look on MSDN: was added in .NET 2.0.

Can't get this working on my computer. System.Management doesn't have ManagementObjectSearcher class now. The URL is also not pointing to a valid web page.

You need to add reference for that. On Visual Studio, Right click on project then go to Add -> Reference. Then, search for "System.Management" and add it.
