一、使用WMI获取

通过WMI获得硬盘和cpu的物理序列号（VB.net）

''获得硬盘序列号

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





''获得cpu序列号

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



''获得硬盘总容量

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；然后在代码中Imports System.Management；
