vb.net – 如何获得PC唯一ID？

我想在我的窗口程序中存储PC ID.请分享我

Private Function CpuId() As String
    Dim computer As String = "."
    Dim wmi As Object = GetObject("winmgmts:" & _
        "{impersonationLevel=impersonate}!\\" & _
        computer & "\root\cimv2")
    Dim processors As Object = wmi.ExecQuery("Select * from " & _
        "Win32_Processor")

    Dim cpu_ids As String = ""
    For Each cpu As Object In processors
        cpu_ids = cpu_ids & ", " & cpu.ProcessorId
    Next cpu
    If cpu_ids.Length > 0 Then cpu_ids = _
        cpu_ids.Substring(2)

    Return cpu_ids
End Function
