這篇文章將為大家詳細講解有關C#中ManagementObjectSearcher怎么用，小編覺得挺實用的，因此分享給大家做個參考，希望大家閱讀完這篇文章后可以有所收獲。
在剛學C#，用ManagementObjectSearcher 竟然不能解析到頭文件，需要手動 Add Referance..
我們在很多情況下想要獲得計算機的硬件或操作系統的信息，比如獲得CPU序列號給自己的軟件添加機器碼鎖綁定指定電腦。又或者想要獲得硬盤分區，聲卡顯卡等信息。
我們用到的主要類是ManagementObjectSearcher,該類在System.Management命名空間下。
有時候我們可以通過Environment獲得一些簡單的系統信息。
如：Environment.MachineName;獲得計算機名。
Environment.UserName;獲得操作系統登錄用戶名。
不過在這篇文章中主要討論ManagementObjectSearcher獲取計算機硬件及操作系統的信息。
添加引用：System.Management
引入命名空間：using System.Management;
創建ManagementObjectSearcher對象
anagementObjectSearcher searcher = new ManagementObjectSearcher("select * from " + Key);
其中的key見下面key列表：
通過searcher.Get()獲得ManagementObjectCollection集合
遍歷ManagementObjectCollection集合獲得ManagementObject
通過managementObject[name]或ManagementObject.GetPropertyValue(name)獲得想要的屬性
若不知道這里的name該寫什么可以遍歷打印一下：
foreach (var property in managementObject.Properties)
{
Console.WriteLine(property.Name+":"+property.Value);
}//獲取CPU序列號
public string GetCPUSerialNumber()
{
try
{
ManagementObjectSearcher searcher = new ManagementObjectSearcher("Select * From Win32_Processor");
string sCPUSerialNumber = "";
foreach (ManagementObject mo in searcher.Get())
{
sCPUSerialNumber = mo["ProcessorId"].ToString().Trim();
break;
}
return sCPUSerialNumber;
}
catch
{
return "";
}
}/獲取主板序列號
public string GetBIOSSerialNumber()
{
try
{
ManagementObjectSearcher searcher = new ManagementObjectSearcher("Select * From Win32_BIOS");
string sBIOSSerialNumber = "";
foreach (ManagementObject mo in searcher.Get())
{
sBIOSSerialNumber = mo.GetPropertyValue("SerialNumber").ToString().Trim();
break;
}
return sBIOSSerialNumber;
}
catch
{
return "";
}
}//獲取硬盤序列號
public string GetHardDiskSerialNumber()
{
try
{
ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia");
string sHardDiskSerialNumber = "";
foreach (ManagementObject mo in searcher.Get())
{
sHardDiskSerialNumber = mo["SerialNumber"].ToString().Trim();
break;
}
return sHardDiskSerialNumber;
}
catch
{
return "";
}
}//獲取網卡地址
public string GetNetCardMACAddress()
{
try
{
ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapter WHERE ((MACAddress Is Not NULL) AND (Manufacturer <> 'Microsoft'))");
string NetCardMACAddress = "";
foreach (ManagementObject mo in searcher.Get())
{
NetCardMACAddress = mo["MACAddress"].ToString().Trim();
break;
}
return NetCardMACAddress;
}
catch
{
return "";
}
}ManagementObjectSearcher searcher = new ManagementObjectSearcher("select * from " + Key);
