How to convert the output of a performance counter to an int in c#

I am having an error when i try to display the current CPU and memory 开发者_Go百科usage using a progress bar. The code seems to be correct as it works with a label, but I am getting an error "Cannot convert to int" so how can I convert the performance counter's data into an int so it can be displayed in a progress bar? I tried using System.Convert.ToInt32(cpuCounter); but it didn't work out for me. Here is my code:

PerformanceCounter ramCounter;
        ramCounter = new PerformanceCounter("Memory", "Available MBytes");
        ramCounter.NextValue();
        progressBar1.Value = ramCounter;

        PerformanceCounter cpuCounter;
        cpuCounter = new PerformanceCounter();
        cpuCounter.CategoryName = "Processor";
        cpuCounter.CounterName = "% Processor Time";
        cpuCounter.InstanceName = "_Total";
        cpuCounter.NextValue();
        progressBar2.Value = cpuCounter;

Thanks!

You need the result of PerformanceCounter.NextValue() - you're currently ignoring it:

float value = cpuCounter.NextValue();
progressBar2.Value = (int) value;

You'll want to check the range of expected values of course - you may well want to scale it.

Another option is to use the RawValue property, which is a long.

You should not assign the Performance Counter instance to your progress bar but its value. The value itself is Int64.

progressbar1.Value = (Int32) ramCounter.RawValue;
