VB.net获取硬盘和CPU物理序列号的实例

首先，引用System.Management；然后在代码中Imports System.Management；

以下功能主要依靠wmi实现

' 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
