与原始的 WMI 相比，使用 .NET Framework 中的 WMI 编写客户端应用程序或提供程序具有多种优势，特别是对于使用 C#（而不是 C++）的开发人员。
在这种情况下，编写提供程序意味着为在托管代码中编写的应用程序添加规范。
在编写客户端应用程序和提供程序时，.NET Framework 中的 WMI 具有下列优势：
-
利用公共语言运行库功能，例如垃圾回收、自定义索引器和字典。
此外，还提供其他公共语言运行库功能，例如自动内存管理、有效部署、面向对象的框架、基于证据的安全性以及异常处理。
-
类定义和实例发布与 .NET Framework 类一起规范化应用程序，以便应用程序可以为 WMI 提供数据。
System.Management.Instrumentation中的类使您能够注册新提供程序、创建新类和发布实例，而不必使用托管对象格式 (MOF) 代码。
-
使用简单。
原始 WMI 的 C++ 应用程序有时很难开发，或开发时间很长。System.Management的类结构为在 .NET Framework 中开发的应用程序带来更多类似脚本的简单性。可以更快地开发应用程序和提供程序，并且更容易调试。
-
可以访问所有 WMI 数据。
与原始 WMI 相比，客户端应用程序可以对 WMI 数据进行相同的访问，并且可以执行所有相同的操作。提供程序规范化的应用程序限制性会更强一些。有关更多信息，请参见.NET Framework 中的 WMI 局限性。
下面例子是使用.NET的WMI实现对系统硬件信息进行获取的代码
