I would like to access information on the logical drives on my computer using C#. How should I accomplish this? Thanks!
For most information, you can use the DriveInfo class.
using System;
using System.IO;
class Info {
public static void Main() {
DriveInfo[] drives = DriveInfo.GetDrives();
foreach (DriveInfo drive in drives) {
//There are more attributes you can use.
//Check the MSDN link for a complete example.
Console.WriteLine(drive.Name);
if (drive.IsReady) Console.WriteLine(drive.TotalSize);
}
}
}
If you want to get information for single/specific drive at your local machine. You can do it as follow using DriveInfo class:
//C Drive Path, this is useful when you are about to find a Drive root from a Location Path.
string path = "C:\\Windows";
//Find its root directory i.e "C:\\"
string rootDir = Directory.GetDirectoryRoot(path);
//Get all information of Drive i.e C
DriveInfo driveInfo = new DriveInfo(rootDir); //you can pass Drive path here e.g DriveInfo("C:\\")
long availableFreeSpace = driveInfo.AvailableFreeSpace;
string driveFormat = driveInfo.DriveFormat;
string name = driveInfo.Name;
long totalSize = driveInfo.TotalSize;
What about mounted volumes, where you have no drive letter?
foreach( ManagementObject volume in
new ManagementObjectSearcher("Select * from Win32_Volume" ).Get())
{
if( volume["FreeSpace"] != null )
{
Console.WriteLine("{0} = {1} out of {2}",
volume["Name"],
ulong.Parse(volume["FreeSpace"].ToString()).ToString("#,##0"),
ulong.Parse(volume["Capacity"].ToString()).ToString("#,##0"));
}
}
使用 System.IO.DriveInfo 类http://msdn.microsoft.com/en-us/library/system.io.driveinfo.aspx
检查DriveInfo类,看看它是否包含您需要的所有信息。
In ASP .NET Core 3.1, if you want to get code that works both on windows and on linux, you can get your drives as follows:
var drives = DriveInfo
.GetDrives()
.Where(d => d.DriveType == DriveType.Fixed)
.Where(d => d.IsReady
.ToArray();
If you don't apply both wheres, you are going to get many drives if you run the code in linux (eg "/dev", "/sys", "/etc/hosts", etc.).
This is specially useful when developing an app to work in a Linux Docker container.
