如何在C＃winforms中获取系统的CPU使用率和内存使用率？ [英] How to get cpu usage and memory usage of the system in C# winforms?

问题描述

在我的应用程序中，我想在每次1秒的间隔中显示cpu和内存使用情况。请帮我详细说明。



我尝试过：



iam使用PerformanceCounter来获取此信息，但它与系统的cpu使用情况不一致。请找到我的应用程序中使用的代码。



PerformanceCounter cpuCounter;

cpuCounter = new PerformanceCounter（Processor，％特权时间，_总计）;

lbl_cpu_usage.Text = Convert.ToInt32（cpuCounter.NextValue（））。ToString（）+％;（此代码写在计时器刻度事件中。

In my application i want to display cpu and memory usage in every time intervel of 1 second. Please help me to get exact details.

What I have tried:

iam using PerformanceCounter to get this information, but it is not correct with cpu usage of system. Please find the the code that are used in my application.

PerformanceCounter cpuCounter;
cpuCounter = new PerformanceCounter("Processor", "% Privileged Time", "_Total");
lbl_cpu_usage.Text = Convert.ToInt32(cpuCounter.NextValue()).ToString() + "%";(This code is written in the timer tick event.

推荐答案

性能计数器对象通常需要两个相隔1到2秒采样的值才能给出准确的读数..虽然我讨厌我的事实在这里使用线程延迟，我想不出更简单的方法 - 看到我添加到你的代码中的两行粗体 - 看看是否使它更准确

Performance counter objects in general need two values sampled at 1 - 2 seconds apart to be able to give accurate readings .. although I hate the fact I'm using a thread delay here, I can't think of a simpler way - see the two lines in bold I've added to your code - see if that makes it more accurate

PerformanceCounter cpuCounter;
cpuCounter = new PerformanceCounter("Processor", "% Privileged Time", "_Total");
cpuCounter.NextValue();  
System.Threading.Thread.Sleep(1000); 
lbl_cpu_usage.Text = Convert.ToInt32(cpuCounter.NextValue()).ToString() + "%";
