使用WMI来获取CPU序列号

//返回的是一个数组，可能存在多个CPU using System; using System.Management; using System.Collections; public ArrayList GetCpuID() { ArrayList al=new ArrayList(); try { ManagementClass mc = new ManagementClass("Win32_Processor"); ManagementObjectCollection moc = mc.GetInstances(); foreach( ManagementObject mo in moc ) { al.Add(mo.Properties["ProcessorId"].Value.ToString()); } return al; } catch（） { return null; } }
