Hi all,

I have a requirement where i need to display the disk space (total size and free space left) for all mapped drives in C# (Asp.net). I'm new to ASP.NET.

I achieved it by the code mentioned below:

C#

protected void DriveInfo_Click(object sender, EventArgs e)
   {
       DriveInfo[] allDrives = DriveInfo.GetDrives();

       foreach (DriveInfo d in allDrives)
       {
           Console.WriteLine("Drive {0}", d.Name);
           Console.WriteLine("  Drive 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);
           }
       }
   }

When i use breakpoint, i got the required information but how to display the data in gridview?

Anyone can help me achieving it? How can i do it?

What I have tried:

I'm trying browsing but as i'm new to asp.net, i'm unable to hold of any particular site casue the terminology is little confusing for me.

That doesn't make sense because ASP.NET code runs entirely on the web server and won't have any mapped drives at all.

If you're talking about the mapped drives on the client (browser) you're still out of luck because code running in the web browser (javascript) doesn't have access to the client machines resources, like drives.

Actually, that drives are mapped to My Computer in my laptop. So from there i have to read the drive name, total size and free space.
So it's not possible?

You're going to have to fill in the details. This still isn't enough information.

So does every other PC in the network have drive letters mapped to the shares exposed by your laptop? Is the IIS server hosting this ASP.NET application running on your laptop?

Actually it's remote machine. So first i want get the MY COMPUTER drive details in my laptop so later i can figure out how to get the same for mapped drives.

I'm afraid to ask: aren't you "required" to get information on client-side volumes? :-)
I'm just curious, because, no matter what disk space is "required" to be read, case closed.

Actually the drivers are mapped to MY COMPUTER in my laptop. I want to read the NAME, TOTAL SIZE and FREE SPACE from it. Isn't it possible?

I guessing this is for an internal website for you employer. Stack has a good example: http://stackoverflow.com/questions/1393711/get-free-disk-space

Regardless of where it is mapped, you have to have access rights to the disk and the disk has to be online (obviously). SO link offers good advice and example code.

Member 8010354 14-Apr-16 3:01am

Normally in My Computer, will have
1) Hard Disk Drives: C, D and etc.
2) Devices with Removable Storage: Floppy Disk Drive, DVD Drive and etc.
3) Network Location: Whatever the networks we mapped will be seen here.

So, what i want is For those, drives there is Total size and Free space which i can see after opening a my computer but i want to automate that. can anyone please hemp me on this?

Why have you updated your question? We have explained to you a number of times that you cannot do this in a browser.

Instead of Console.WriteLine, Use Response.write to display it on web page.
or add labels to your page and set text of label with the values.

See DriveInfo.AvailableFreeSpace Property (System.IO)[^].

Hi, Thank you providing it. I tried this code but when i execute, i see blank screen in output. Can you let me know where did i missed like i'm not getting any error as well.

Member 8010354 14-Apr-16 3:50am

Below is my program:

public partial class DriveThreshold : System.Web.UI.Page
{
class Report
{
public static void Main()
{
DriveInfo[] allDrives = DriveInfo.GetDrives();

foreach (DriveInfo d in allDrives)
{
Console.WriteLine("Drive {0}", d.Name);
Console.WriteLine(" Drive 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);
}
}
}
}

In ASPX page:

<div>
<asp:Button ID="DriveInfor" runat="server" Text="Get the Drive Info" OnClick="DriveInfo_Click" />
</div>

As explained earlier you are getting information on the drives connected to the server. You cannot do this from a web browser.

Member 8010354 14-Apr-16 4:34am

@Richard: Can you please suggest me which way to go.

Richard MacCutchan 14-Apr-16 5:08am

Which way to go for what? We have explained that you cannot do this in a browser. So your only option is to create a desktop application that produces the information.

Member 8010354 14-Apr-16 5:10am

Desktop application means a windows application?

Richard MacCutchan 14-Apr-16 5:12am

Yes.

Mapped drives are not actual drives. they are folder/directories in a machine in your network.
you are saving their path as drive, so the free space or used space you will see is the space of that folder's drive.

Required c# code will be

using System.IO;

foreach (var item in drives)
{
Console.WriteLine("Drive: {0} TotalSpace:{1} FreeSpace:{2}",item.Name,item.TotalSize ,item.AvailableFreeSpace);
}
