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?
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();
}
