.net核心中的CPU使用率（至少在Windows上） [英] CPU usage in .net core (at least on Windows)
问题描述
因此 PerformanceCounter 不在dotnet核心中了。我了解这是因为它不兼容Linux。
So PerformanceCounter is gone in dotnet core. I understand it was because it was not Linux-compatible.
此处的注释：（。NET Core的性能计数器的故事是什么？）似乎表明如果我愿意运行它仅在Windows上，我可以利用Windows特定的功能，但是我不知道如何将其集成到dotnet核心中。
This comment here: ( What is the story of Performance Counters for .NET Core? ) seems to suggest that if I was willing to run it only on Windows I could "make use of Windows-specific features", but I don't know how I could integrate that in dotnet core.
我愿意的原因解决此问题的方法是保留dotnet核心代码库，这样，一旦有针对 PerformanceCounter 的跨平台解决方案，我就不必迁移。
The reason I am willing to do this workaround is to keep the dotnet core codebase so I don't have to migrate once there is a cross-platform solution for PerformanceCounter.
总结一下我的问题：在Windows上运行时如何在dotnet core中运行CPU使用情况？
So to summarize my question: how can I run the CPU usage in dotnet core when running on Windows?

此解决方案似乎暗示t
Process.GetCurrentProcess（）就足够了，我不太理解（PerformanceCounter提供了完整的CPU使用率
This solution seems to suggest that
Process.GetCurrentProcess()would be enough, which I don't quite understand (PerformanceCounterprovided the full CPU usage for the machine).
遍历所有进程（如这另一篇文章似乎暗示？）是不可行的（它为某些进程引发了异常），而且看起来也很慢，这对我的用例来说是个问题。
Looping through all processes (as this other post seem to suggest?) is not feasible (it throws an exception for some processes) and it looks pretty slow as well which is a problem for my use case.
推荐答案
从.NET Core 3.0开始，Performance Counter API曾经是再次成为BCL的一部分，并且也支持Linux：
As of .NET Core 3.0, the Performance Counter APIs are once again part of the BCL and support Linux too:
