 //由以上各步看出，通过Win32_Processor获取CPUID不正确，或者说Win32_Processor字段就不包含CPU编号信息。

 //通过Win32_BaseBoard获取主板信息，但不是所有的主板都有编号，或者说不是能获取所有系统主板的编号。

 //通过Win32_PhysicalMedia获取硬盘编号应该没有问题。但网上说可以通过Win32_DiskDrive获取，其实所得信息根本不包含SerialNumber。

 //通过Win32_BIOS获取BIOS信息，基本和获取主板信息差不多。就是说：不是所有的主板BIOS信息都有编号。

 //另外，可以将通过以上各字段所得信息输出，逐个查看所有信息 属性和对应的值。代码如下：

 view plaincopy to clipboardprint?
 ManagementClass mc = new ManagementClass("Win32_Processor");
 ManagementObjectCollection moc = mc.GetInstances();
 foreach( ManagementObject mo in moc )

 {
 textBox1.Text += pd.Value.ToString();
 }
