然后遍历ds，获取各个信息部分。

Dim ds() As System.IO.DriveInfo = System.IO.DriveInfo.GetDrives()

For i As Integer = 0 To ds.Length - 1

TextBox1.Text = TextBox1.Text + ds(i).DriveType.ToString + " " '驱动器类型

TextBox1.Text = TextBox1.Text + ds(i).Name + " " '盘符（驱动器名）

TextBox1.Text = TextBox1.Text + ds(i).IsReady.ToString + " " '是否就绪

If ds(i).IsReady = True Then

TextBox1.Text = TextBox1.Text + ds(i).VolumeLabel + " " '卷标

TextBox1.Text = TextBox1.Text + ds(i).TotalSize.ToString + " " '驱动器容量

TextBox1.Text = TextBox1.Text + ds(i).TotalFreeSpace.ToString '驱动器可用容量

End If

TextBox1.Text = TextBox1.Text + vbNewLine

关于 VB.NET 2008中U盘的插拔

一下代码将自动完成检测：

Imports System.IO

Public Class Form1

Public Const WM_DEVICECHANGE = H219

Public Const DBT_DEVICEARRIVAL = H8000

Public Const DBT_DEVICEREMOVECOMPLETE = H8004

Dim DriveLetter As String

Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message)

If m.Msg = WM_DEVICECHANGE Then

Select Case m.WParam

Case DBT_DEVICEARRIVAL

Dim s() As DriveInfo = DriveInfo.GetDrives

For Each drive As DriveInfo In s

If drive.DriveType = DriveType.Removable Then

DriveLetter = drive.Name.ToString()

Debug.WriteLine("U盘 :" DriveLetter "已插入.")

End If

Next

Case DBT_DEVICEREMOVECOMPLETE

Dim s() As DriveInfo = DriveInfo.GetDrives

For Each drive As DriveInfo In s

If drive.ToString = DriveLetter Then Exit Sub

Next

Debug.WriteLine("U盘:" DriveLetter "已卸载！")

End Select

End If

MyBase.WndProc(m)

End Sub

End Class

Vb如何获取系统卷标磁盘名字各是什么? 急求,谢啦

添加对应DriveListBox控件

代码如下：

n = Drive1.ListCount

For i = 0 To n - 1

Drive1.ListIndex = i

DrvName = Left(Drive1.Drive, 2)'这是盘符名

DrvLabel = Mid(Drive1.Drive, 3, Len(Drive1.Drive) - 2) '这是卷标名

'需要说明的是：卷标名如果为默认名称，读到是空的，可加个if显示为“本地磁盘”

Print DrvName, DrvLabel

Next i
