Question

Im making a app that monitors stuff on my computer, and i want to make it somewhat more difficult then just implementing a while loop.

So my question is how do i do it if i would like to fetch cpu load in a seperate thread, that updates a static variable in class

namespace threads
{
    class Program
    {
        static int cpuload = 0;

        static void Main(string[] args)
        {
            while (true)
            {
                Thread th = new Thread(new ThreadStart(CheckCPULoad));
                th.Start();

                Thread.Sleep(1000); // sleep the main thread

                th.Abort();

                Console.WriteLine("load: {0}%", cpuload);
            }
        }

        static void CheckCPULoad()
        {
            // things are updated every 3 secs, dummy data
            Thread.Sleep(3000);

            Random rnd = new Random();
            cpuload++;// = rnd.Next(0, 100); // dummy data
        }
    }
}

As it is “load: 0%” is printed every time. what do i need to fix to make it show

load: 0% 
load: 0% 
load: 0% 

?

thanks

If i get you right, this should solve your purpose. Notice the while loop inside the CheckCPULoad() method.

class Program 
        {
            static int cpuload = 0;

    static void Main(string[] args)
    {
        Thread th = new Thread(new ThreadStart(CheckCPULoad));
        th.Start();

        while (true)
        {
            Thread.Sleep(1000);
            Console.WriteLine("load: {0}%", cpuload);
        }
        th.Abort(); // Don't ever reach this line with while (true)        
    }

    static void CheckCPULoad()
    {
        while (true)
        {
            Thread.Sleep(3000);
            cpuload++;
        }
    }


}
