今天玩了一把WMI,查詢了一下電腦的硬件信息,感覺很多代碼都是可以提取出來的,就自己把那些公共部分提出出來,以后如果要獲取某部分的硬件信息就不用寫一個一個的函數,比如獲取MAC地址就寫一個獲取MAC地址的函數,獲取CPU 信息就寫一個獲取CPU信息的函數,太麻煩了
如下是函數代碼:
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;
}
獲取CPUID
private static string cpuId()
{
string retVal = identifier("Win32_Processor", "UniqueId"); //CPUID
retVal += identifier("Win32_Processor", "ProcessorId");
retVal += identifier("Win32_Processor", "Name"); //處理器名稱
retVal += identifier("Win32_Processor", "Manufacturer"); //處理器制造商
retVal +=identifier("Win32_Processor", "MaxClockSpeed"); //最大時鐘頻率
return retVal;
}
獲取BIOS信息,其中BIOS序列號就是聯想臺式機的出廠編號,我看聯想的保修頁面里的自動獲取主機編號應該也是調用這個"Win32_BIOS"的 "SerialNumber
報修頁面網址:http://support1.lenovo.com.cn/lenovo/wsi/wsbx/lenovo/#minarepairInfo
//BIOS信息
private static string biosId()
{
return identifier("Win32_BIOS", "Manufacturer") //BIOS制造商名稱
+ identifier("Win32_BIOS", "SMBIOSBIOSVersion") //
+ identifier("Win32_BIOS", "IdentificationCode") //
+ identifier("Win32_BIOS", "SerialNumber") //BIOS序列號
+ identifier("Win32_BIOS", "ReleaseDate") //出廠日期
+ identifier("Win32_BIOS", "Version"); //版本號
}
獲取硬盤信息:
private static string diskId()
{
return identifier("Win32_DiskDrive", "Model") //模式
+ identifier("Win32_DiskDrive", "Manufacturer") //制造商
+ identifier("Win32_DiskDrive", "Signature") //簽名
+ identifier("Win32_DiskDrive", "TotalHeads"); //扇區頭
}
獲取顯卡信息:
private static string videoId()
{
return identifier("Win32_VideoController", "DriverVersion")
+ identifier("Win32_VideoController", "Name");
}
獲取網卡MAC地址信息:
private static string macId()
{
return identifier("Win32_NetworkAdapterConfiguration", "MACAddress", "IPEnabled");
}
