Public Property VolumeLabel As String
The volume label.
- Attributes
An I/O error occurred (for example, a disk error or a drive was not ready).
The drive is not mapped or does not exist.
The caller does not have the required permission.
The volume label is being set on a network or CD-ROM drive.
-or-
Access to the drive information is denied.
The following example demonstrates the use of the DriveInfo class to display information about all the drives on the current system.
using System;
using System.IO;
class Test
{
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);
}
}
}
