C Sharp 中的 ManagementClass 类和获取硬件的信息的用法
C Sharp 中的 ManagementClass 类和获取硬件的信息的用法
在. NET 的项目中，有时候需要获取计算机的硬件的相关信息，在 C# 语言中需要利用 ManagementClass 这个类来进行相关操作。
ManagementClass 类: 对表示一个通用信息模型 (CIM) 管理类。管理类是 WMI 类，如 Win32_LogicalDisk，该类型可表示一个磁盘驱动器，并 Win32_Process，它表示的进程 Notepad. exe 等。此类的成员可以访问 WMI 数据，使用一个特定的 WMI 类路径。
继承层次结构：
System.Object
System.MarshalByRefObject
System.ComponentModel.Component
System.Management.ManagementBaseObject
System.Management.ManagementObject
System.Management.ManagementClass
- GetInstances（）：此方法存在四个重载
| 方法名 | 作用 |
|---|---|
| GetInstance () | 返回类的所有实例集合 |
| GetInstance (EnumerationOptions) | 返回使用指定选项的类的所有实例的集合 |
| GetInstance (ManagementOperationObserver) | 以异步方式返回类的所有实例的集合 |
| GetInstance (ManagementOperationObserver, EnumerationOptions) | 使用指定的选项以异步方式返回类的所有实例的集合 |
- Get ()：
| 方法名 | 作用 |
|---|---|
| Get () | 将 WMI 类信息绑定到管理对象 |
| Get (ManagementOperationObserver) | 将以异步方式绑定到管理对象 |
- GetSubclasses（）：此方法存在四个重载版本
| 方法名 | 作用 |
|---|---|
| GetSubclasses () | 返回所有子类的类的集合 |
| GetSubclasses (EnumerationOptions) | 检索使用指定选项的类的子类 |
| GetSubclasses（ManagementOperationObserver） | 返回所有以异步方式从该类派生的类的集合 |
| GetSubclasses（ManagementOperationObserver, EnumerationOptions） | 检索所有以异步方式派生自此类并使用指定选项的子类 |
C# 提供了 ManagementClass 类来获取本机的一些基本信息，比如 CPU 的个数，CPU 的频率，网卡的 MAC，内存的大小，硬盘的大小等。
