WMI获取硬件信息封装函数方法(联想台式机出厂编号 CPUID BIOS序列号 硬盘信息 显卡信息 MAC地址)

今天玩了一把wmi，查询了一下电脑的硬件信息，感觉很多代码都是可以提取出来的，就自己把那些公共部分提出出来，以后如果要获取某部分的硬件信息就不用写一个一个的函数，比如获取mac地址就写一个获取mac地址的函数，获取cpu 信息就写一个获取cpu信息的函数，太麻烦了

如下是函数代码：

private static string identifier(string wmiclass, string wmiproperty, string wmimustbetrue)
        {
            string result = "";
            system.management.managementclass mc = new system.management.managementclass(wmiclass);
            system.management.managementobjectcollection moc = mc.getinstances();
            foreach (system.management.managementobject mo in moc)
            {
                if (mo[wmimustbetrue].tostring() == "true")
                {
                    if (result == "")
                    {
                        try
                        {
                            result = mo[wmiproperty].tostring();
                            break;
                        }
                        catch
                        {
                        }
                    }

                }
            }
            return result;
        }

        private static string identifier(string wmiclass, string wmiproperty)
        {
            string result = "";
            system.management.managementclass mc = new system.management.managementclass(wmiclass);
            system.management.managementobjectcollection moc = mc.getinstances();
            foreach (system.management.managementobject mo in moc)
            {
                if (result == "")
                {
                    try
                    {
                        result = mo[wmiproperty].tostring();
                        break;
                    }
                    catch
                    {
                    }
                }

            }
            return result;
        }

获取cpuid

private static string cpuid()
        {    
            string retval = identifier("win32_processor", "uniqueid");  //cpuid  
            retval += identifier("win32_processor", "processorid");
            retval += identifier("win32_processor", "name");  //处理器名称
            retval += identifier("win32_processor", "manufacturer");  //处理器制造商
            retval +=identifier("win32_processor", "maxclockspeed");  //最大时钟频率
            return retval;
        }

获取bios信息，其中bios序列号就是联想台式机的出厂编号，我看联想的保修页面里的自动获取主机编号应该也是调用这个"win32_bios"的 "serialnumber

报修页面网址：http://support1.lenovo.com.cn/lenovo/wsi/wsbx/lenovo/#minarepairinfo

//bios信息
        private static string biosid()
        {
            return identifier("win32_bios", "manufacturer")          //bios制造商名称
                    + identifier("win32_bios", "smbiosbiosversion")  //
                    + identifier("win32_bios", "identificationcode") //
                    + identifier("win32_bios", "serialnumber")       //bios序列号
                    + identifier("win32_bios", "releasedate")        //出厂日期
                    + identifier("win32_bios", "version");           //版本号
        }

获取硬盘信息：

private static string diskid()
        {
            return identifier("win32_diskdrive", "model")           //模式
                    + identifier("win32_diskdrive", "manufacturer") //制造商
                    + identifier("win32_diskdrive", "signature")    //签名
                    + identifier("win32_diskdrive", "totalheads");  //扇区头
        }

获取显卡信息：

private static string videoid()
         {
            return identifier("win32_videocontroller", "driverversion")
                     + identifier("win32_videocontroller", "name");
        }

获取网卡mac地址信息：

private static string macid()
         {
             return identifier("win32_networkadapterconfiguration", "macaddress", "ipenabled");
        }
