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。

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

Next

vb6怎样读取win10下硬盘序列号

vb6读取win10下硬盘序列号方法如下：

1、是指硬盘物理序列号，格式化没有变化。

2、支持vista 及win10系统。

3、支持多块硬盘（有的电脑装有几块硬盘）

4、支持串口及并口硬盘。

5、最好是源码或dll 等，代码如下：

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）。

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！
