Question

I’m a bit rusty on my mathematics so I hope someone can help me. Using the code below I would like to do the following: Depending on the amount of memory installed, I would like to display the percentage of available memory and not how much is left in megabytes.

private void timer1_Tick(object sender, EventArgs e)
{
    string memory;
    int mem;
    memory = GetTotalMemoryInBytes().ToString();
    mem = Convert.ToInt32(memory);
    mem = mem / 1048576; 
    progressBar2.Maximum = mem;
    progressBar2.Value = mem - (int)(performanceCounter2.NextValue());
    label2.Text = "Available Memory: " + (int)(performanceCounter2.NextValue()) + "Mb"; 


}

//using Microsoft visual dll reference in c#
static ulong GetTotalMemoryInBytes()
{
    return new Microsoft.VisualBasic.Devices.ComputerInfo().TotalPhysicalMemory;
}

Answer 1

(Available memory / Total memory) * 100 will be your percentage.

double percent = ((performanceCounter2.NextValue() * 1.0) / mem) * 100;
label2.Text = "Available Memory: " + percent;
