How to fetch task manager "Performance" tab values?

For CPU Usage

==============

create a private static member like so:

static PerformanceCounter cpuCounter;

in the constructor of the form add this code:

public Form1()

{

InitializeComponent();

cpuCounter = new PerformanceCounter();

cpuCounter.CategoryName = "Processor";

cpuCounter.CounterName = "% Processor Time";

cpuCounter.InstanceName = "_Total";

}

and use this as a property, like so:

public static string CurrentCPUusage

{

get

{

return cpuCounter.NextValue() + "%";

}

And use it like:

label1.Text = CurrentCPUusage;

You need to add it like this because it has to monitor the CPU in order to get the current value.

For Physical Memory

================

[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)]

private class MEMORYSTATUSEX

{

public uint dwLength;

public uint dwMemoryLoad;

public ulong ullTotalPhys;

public ulong ullAvailPhys;

public ulong ullTotalPageFile;

public ulong ullAvailPageFile;

public ulong ullTotalVirtual;

public ulong ullAvailVirtual;

public ulong ullAvailExtendedVirtual;

public MEMORYSTATUSEX()

{

this.dwLength = (uint)Marshal.SizeOf(typeof(NativeMethods.MEMORYSTATUSEX));

}

[return: MarshalAs(UnmanagedType.Bool)]

[DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)]

static extern bool GlobalMemoryStatusEx([In, Out] MEMORYSTATUSEX lpBuffer);

Then use like:

ulong installedMemory;

MEMORYSTATUSEX memStatus = new MEMORYSTATUSEX();

if( GlobalMemoryStatusEx( memStatus))

{

installedMemory = memStatus.ullTotalPhys;

}

Or you can use WMI (managed but slower) to query "TotalPhysicalMemory" in the "Win32_ComputerSystem" class.

For System Properties

======================

System.Environment.SetEnvironmentVariable("webdriver.chrome.driver",@"/path/to/where/you/ve/put/chromedriver.exe")

Hope this may helps you. Thanks in Advance.
