如何在 .Net Core 中获取进程的 CPU 使用率和虚拟内存?

问题描述

在 .NET Core 中，如何获取给定进程的 CPU 使用率和虚拟内存?

In .NET Core, how to get the CPU usage and Virtual Memory for a given process?

Google 搜索结果显示 PerformanceCounter 和 DriverInfo 类可以完成这项工作.然而，PerformanceCounter &DriverInfo 类在 .NET Core 中不可用.

Google search result reveals that PerformanceCounter and DriverInfo class could do the job. However, PerformanceCounter & DriverInfo class are not available in .NET Core.

stackoverflow 中有一篇关于这个问题的帖子:如何在使用 .NET CORE 的 C# Web 应用程序中获取当前 CPU/RAM/磁盘使用情况?

There is a post in stackoverflow about this question: How to get the current CPU/RAM/Disk usage in a C# web application using .NET CORE?

但是它只解决:-当前进程的CPU使用率:

However it only addresses:-CPU usage for the current process:

    var proc = Process.GetCurrentProcess();

我已获得进程(使用 ProcessID 整数格式).如何在 .NET Core 中获取该特定进程的 CPU 使用率和虚拟内存?

I have been given process (with a ProcessID integer format). How do I get the CPU Usage and Virtual Memory for that particular process in .NET Core?

推荐答案

您可以在 System.Diagnostics.PerformanceCounter 包

例如，下一个代码将为您提供总处理器使用百分比

for example, the next code will give you the total processor usage percent

var cpuCounter = new PerformanceCounter("Processor", "% Processor Time", "_Total", true);
var value = cpuCounter.NextValue();
// In most cases you need to call .NextValue() twice
if (Math.Abs(value) <= 0.00)
    value = cpuCounter.NextValue();

Console.WriteLine(value);
