vb.net调用硬盘信息的简单介绍

vb.net如何获取电脑中的所有盘符

首先使用 System.IO.DriveInfo.GetDrives()获取System.IO.DriveInfo,存入ds()

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

win7下vb.net 如何获取硬盘序列号

Private Function 硬盘序列号() As String

Try

Dim myInfo As Microsoft.Win32.RegistryKey = My.Computer.Registry.LocalMachine.OpenSubKey("HARDWARE\DEVICEMAP\Scsi\Scsi Port 0\Scsi Bus 1\Target Id 0\Logical Unit Id 0")

硬盘序列号 = Trim(myInfo.GetValue("SerialNumber"))

Catch

Try

Dim myInfo As Microsoft.Win32.RegistryKey = My.Computer.Registry.LocalMachine.OpenSubKey("HARDWARE\DEVICEMAP\Scsi\Scsi Port 1\Scsi Bus 1\Target Id 0\Logical Unit Id 0")

硬盘序列号 = Trim(myInfo.GetValue("SerialNumber"))

Catch

硬盘序列号 = ""

End Try

End Try

End Function

试下,如果返回为空,则表示失败。

在本机win8win8.1有效,不过好像在有些机器上没用。

VB6中如何获取磁盘信息?

楼上的朋友可能有点小小的误会楼主的意思了,

楼主朋友可能要现在已经分好区的空间大小,已用空间、剩余空间。

当然我也不敢保证谁对谁错,

我还是把我的理解 然后 也把代码贴出来让楼主看看吧

下面代码的功能:显示光驱当前分区,以及各个盘的总空间,剩余空间。

当然。如果要硬盘总空间,我们可以把所有空间加起来,就达到要求了。

希望下面的代码对楼主有用!

'硬盘空间大小 以及光驱

'添加Drive1 Label1 Label2

Private Declare Function GetDiskFreeSpace Lib "kernel32" Alias "GetDiskFreeSpaceA" (ByVal lpRootPathName As String, lpSectorsPerCluster As Long, lpBytesPerSector As Long, lpNumberOfFreeClusters As Long, lpTtoalNumberOfClusters As Long) As Long

Private Declare Function GetDriveType Lib "kernel32" Alias "GetDriveTypeA" (ByVal nDrive As String) As Long

Const DRIVE_CDROM = 5

Public drivenm As String, cddrive As String

Private Sub Form_Load()

'查找CD-ROM的驱动器号

cddrive = ""

For i = 65 To 90

If GetDriveType(Chr$(i) ":\") = DRIVE_CDROM Then

cddrive = UCase(Chr$(i)) ":\"

Exit For

End If

Next i

drivenm = "c:"

Label1.AutoSize = True

Label2.AutoSize = True

Drive1.Left = (Me.Width - Drive1.Width) \ 2

Drive1.Drive = "c"

Me.Move (Screen.Width - Me.Width) \ 2, (Screen.Height - Me.Height) \ 2

gethd

End Sub

Private Sub Form_Activate()

MsgBox "你的光驱在:" cddrive

End Sub

Private Sub Drive1_Change()

drivenm = Mid(Drive1.Drive, 1, 3)

gethd

End Sub

Private Sub gethd() '得知硬盘容量

Dim dfs, cl1, cl2, sec1, byt1, tspace, getdiskvolm, lSize, kk%

Dim hdtype$, hdspace$, hdfspace$

If dfs Then

cl2 = Int(cl2 * sec1 / 1024 * byt1)

lSize = Len(Format$(cl2, "#########"))

If lSize 11 Then

kk = 11 - lSize

End If

hdspace = Space(kk) + Format$(cl2, "#########") + " KBytes"

Else

MsgBox "这张盘不是空的光盘,但还有空间"

Else

If Val(Label1.Caption) 0 And Val(Label2.Caption) = 0 Then

MsgBox "这张盘是写满并终止的光盘"

End If

End If

End If

End If

VB.NET获取硬盘信息的几种方法

strResult += 磁盘类型: System.Convert.ToInt16(disk(DriveType).ToString())End IfMsgBox(strResult)NextEnd Sub总结:在VB.NET中,用API函数可以获取硬盘信息。原来熟悉API函数VB6程序员,可以对API函数声明进行适当的更改后,进行调用。利用FSO(文件系统对象)的Scrrun.DLL,也可以获得磁盘信息。在.net Framwork中,利用WMI可以获取更多的关于机器硬件的详细信息(参考System.Management命名空间)。
