How to fetch task manager "Performance" tab values?

Question

Hi all, I want to fetch the property values from task manager's performance tabs like CPU usage, Memory , Physical memory, system memory and system properties in c#. Please help me TIA

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.
