Get CPU and RAM usage in C#

Get CPU and RAM usage in C#

In C#, you can get the CPU and RAM usage of the system using the PerformanceCounter class from the System.Diagnostics namespace.

Here is an example code that shows how to get the CPU and RAM usage in C#:

using System;
using System.Diagnostics;

class Program
{
    static void Main(string[] args)
    {
        // Get the CPU usage counter
        PerformanceCounter cpuCounter = new PerformanceCounter("Processor", "% Processor Time", "_Total");

        // Get the RAM usage counter
        PerformanceCounter ramCounter = new PerformanceCounter("Memory", "Available MBytes");

        // Get the current CPU usage
        float cpuUsage = cpuCounter.NextValue();

        // Get the current available RAM in MB
        float availableRAM = ramCounter.NextValue();

        // Wait for one second to get a new measurement
        System.Threading.Thread.Sleep(1000);

        // Get the new CPU usage
        cpuUsage = cpuCounter.NextValue();

        // Get the new available RAM in MB
        availableRAM = ramCounter.NextValue();

        // Output the CPU and RAM usage
        Console.WriteLine("CPU Usage: {0}%", cpuUsage);
        Console.WriteLine("Available RAM: {0} MB", availableRAM);
    }
}

This code creates two PerformanceCounter instances for the CPU usage and RAM usage. It then gets the initial CPU and RAM usage values using the NextValue method. After waiting for one second, it gets the new CPU and RAM usage values and outputs them to the console.

Note that the CPU usage counter may return values above 100% if there are multiple cores or hyper-threading enabled on the system. Also, the RAM usage counter returns the available RAM in MB, not the total amount of RAM or the amount of RAM used by the current process.
