How can I check for available disk space?

Question

I need a way to check available disk space on a remote Windows server before copying files to that server. Using this method I can check to see if the primary server is full and if it is, then I'll copy the files to a secondary server.

How can I check for available disk space using C#/ASP.net 2.0?

Answer 1

You can check it by doing the following:

Add the System.Management.dll as a reference to your project.

Use the following code to get the diskspace:

using System; using System.Management;  public string GetFreeSpace(); {     ManagementObject disk = new ManagementObject("win32_logicaldisk.deviceid=\"c:\"");    disk.Get();    string freespace = disk["FreeSpace"];    return freespace; } 

There are a myriad of ways to do it, I'd check the System.Management namespace for more ways.

Here's one such way from that page:

public void GetDiskspace()     {       ConnectionOptions options = new ConnectionOptions();       ManagementScope scope = new ManagementScope("\\\\localhost\\root\\cimv2",        options);       scope.Connect();       ObjectQuery query = new ObjectQuery("SELECT * FROM Win32_OperatingSystem");       SelectQuery query1 = new SelectQuery("Select * from Win32_LogicalDisk");        ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);       ManagementObjectCollection queryCollection = searcher.Get();       ManagementObjectSearcher searcher1 = new ManagementObjectSearcher(scope, query1);       ManagementObjectCollection queryCollection1 = searcher1.Get();        foreach (ManagementObject m in queryCollection)       {           // Display the remote computer information            Console.WriteLine("Computer Name : {0}", m["csname"]);           Console.WriteLine("Windows Directory : {0}", m["WindowsDirectory"]);           Console.WriteLine("Operating System: {0}", m["Caption"]);           Console.WriteLine("Version: {0}", m["Version"]);           Console.WriteLine("Manufacturer : {0}", m["Manufacturer"]);           Console.WriteLine();       }        foreach (ManagementObject mo in queryCollection1)       {           // Display Logical Disks information           Console.WriteLine("              Disk Name : {0}", mo["Name"]);          Console.WriteLine("              Disk Size : {0}", mo["Size"]);          Console.WriteLine("              FreeSpace : {0}", mo["FreeSpace"]);          Console.WriteLine("          Disk DeviceID : {0}", mo["DeviceID"]);          Console.WriteLine("        Disk VolumeName : {0}", mo["VolumeName"]);          Console.WriteLine("        Disk SystemName : {0}", mo["SystemName"]);          Console.WriteLine("Disk VolumeSerialNumber : {0}", mo["VolumeSerialNumber"]);          Console.WriteLine();       }       string line;       line = Console.ReadLine();      }
