通过WMI获得硬盘和CPU的物理序列号（VB.net）

原文章 ：http://blog.csdn.net/21aspnet/article/details/159124

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

 '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
