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"); }
