通過WMI獲得硬盤和CPU的物理序列號（VB.net）

'獲得硬盤序列號
Dim cmicWmi As New System.Management.ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive")

Dim Uint32 As UInt32

For Each cmicWmiObj As ManagementObject In cmicWmi.Get

Uint32 = cmicWmiObj("signature")

Next

TextBox1.Text = Uint32.ToString

'獲得CPU序列號

Dim Wmi As New System.Management.ManagementObjectSearcher("SELECT * FROM Win32_Processor")

Dim Uint32 As String

For Each WmiObj As ManagementObject In Wmi.Get

Uint32 = WmiObj("ProcessorId")

Next

TextBox1.Text = Uint32

'獲得硬盤總容量

Dim Wmi As New System.Management.ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive")

Dim Uint64 As UInt64

For Each WmiObj As ManagementObject In Wmi.Get

Uint64 = WmiObj("size")

Next

TextBox1.Text = Uint64.ToString

首先，引用System.Management；然後在代碼中Imports System.Management；
