C#使用ManagementClass获取计算器硬件信息
目前我了解的获取硬件信息主要有三种方式，具体如下：
1、读取注册表。
2、使用系统API。
３、使用ManagementClass。
下面主要说说如果使用ManagementClass类来获取计算机上CPU、内存、硬盘、网卡、显示、声卡等信息。
1、新建Console控制台项目。
２、添加ManagementClass类引用。
３、定义要获取硬件类型枚举，不创建枚举类型也可以，在创建ManagementClass对象时直接传字符串。
public enum WindowsAPIType
{
///
/// 内存
///
Win32_PhysicalMemory,
///
/// cpu
///
Win32_Processor,
///
/// 硬盘
///
win32_DiskDrive,
///
/// 电脑型号
///
Win32_ComputerSystemProduct,
///
/// 分辨率
///
Win32_DesktopMonitor,
///
/// 显卡
///
Win32_VideoController,
///
/// 操作系统
///
Win32_OperatingSystem
}4、硬件信息是以键值对形式返回的，所以在定义要获取信息的键值枚举。
public enum WindowsAPIKeys
{
///
/// 名称
///
Name,
///
/// 显卡芯片
///
VideoProcessor,
///
/// 显存大小
///
AdapterRAM,
///
/// 分辨率宽
///
ScreenWidth,
///
/// 分辨率高
///
ScreenHeight,
///
/// 电脑型号
///
Version,
///
/// 硬盘容量
///
Size,
///
/// 内存容量
///
Capacity,
///
/// cpu核心数
///
NumberOfCores
}５、创建获取硬件信息单例类
public class Computer
{
private static Computer _instance;
private static readonly object _lock = new object();
private Computer()
{ }
public static Computer CreateComputer()
{
if (_instance == null)
{
lock (_lock)
{
if (_instance == null)
{
_instance = new Computer();
}
}
}
return _instance;
}
public string GetMACString()
{
ManagementClass mAdapter = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection mo = mAdapter.GetInstances();
foreach (ManagementBaseObject m in mo)
{
if ((bool)m["IpEnabled"] == true)
{
return m["MacAddress"].ToString();
}
}
mo.Dispose();
return null;
}
///
/// 查找cpu的名称，主频, 核心数
///
/// GetCPU()
{
Tuple result = null;
try
{
string str = string.Empty;
ManagementClass mcCPU = new ManagementClass(WindowsAPIType.Win32_Processor.ToString());
ManagementObjectCollection mocCPU = mcCPU.GetInstances();
foreach (ManagementObject m in mocCPU)
{
string name = m[WindowsAPIKeys.Name.ToString()].ToString();
string[] parts = name.Split('@');
result = new Tuple(parts[0].Split('-')[0] + "处理器", parts[1]);
break;
}
}
catch
{
}
return result;
}
///
/// 获取CPU的个数
///
///
/// 获取CPU的频率 这里之所以使用string类型的数组，主要是因为cpu的多核
///
///
/// 获取cpu核心数
///
///
/// 操作系统类型
///
///
/// 获取系统内存大小
///
/// 内存大小（单位M）
public string GetPhisicalMemory()
{
ManagementObjectSearcher searcher = new ManagementObjectSearcher(); //用于查询一些如系统信息的管理对象
searcher.Query = new SelectQuery(WindowsAPIType.Win32_PhysicalMemory.ToString(), "",
new string[] { WindowsAPIKeys.Capacity.ToString() });//设置查询条件
ManagementObjectCollection collection = searcher.Get(); //获取内存容量
ManagementObjectCollection.ManagementObjectEnumerator em = collection.GetEnumerator();
long capacity = 0;
while (em.MoveNext())
{
ManagementBaseObject baseObj = em.Current;
if (baseObj.Properties[WindowsAPIKeys.Capacity.ToString()].Value != null)
{
try
{
capacity += long.Parse(baseObj.Properties[WindowsAPIKeys.Capacity.ToString()].Value.ToString());
}
catch
{
return "查询失败";
}
}
}
return ToGB((double)capacity, 1024.0);
}
