Look here for details   private PerformanceCounter cpuCounter  private PerformanceCounter ramCounter  public Form1         InitializeComponent        InitialiseCPUCounter        InitializeRAMCounter        updateTimer Start       private void updateTimer Tick object sender  EventArgs e        this textBox1 Text    CPU Usage          Convert ToInt32 cpuCounter NextValue    ToString                   this textBox2 Text   Convert ToInt32 ramCounter NextValue    ToString    Mb      private void Form1 Load object sender  EventArgs e       private void InitialiseCPUCounter         cpuCounter   new PerformanceCounter       Processor          Processor Time         Total       true           private void InitializeRAMCounter         ramCounter   new PerformanceCounter  Memory    Available MBytes   true        If you get value as 0 it need to call NextValue   twice  Then it gives the actual value of CPU usage  See more details here

You might want to check the GC GetTotalMemory method   It retrieves the number of bytes currently thought to be allocated by the garbage collector

System Environment has WorkingSet- a 64-bit signed integer containing the number of bytes of physical memory mapped to the process context   If you want a lot of details there is System Diagnostics PerformanceCounter  but it will be a bit more effort to setup

In addition to  JesperFyhrKnudsen s answer and  MathiasLykkegaardLorenzen s comment  you d better dispose the returned Process after using it   So  In order to dispose the Process  you could wrap it in a using scope or calling Dispose on the returned process  proc variable     using scope   var memory   0 0  using  Process proc   Process GetCurrentProcess             The proc PrivateMemorySize64 will returns the private memory usage in byte         Would like to Convert it to Megabyte  divide it by 2 20        memory   proc PrivateMemorySize64    1024 1024      Or Dispose method   var memory   0 0  Process proc   Process GetCurrentProcess    memory   Math Round proc PrivateMemorySize64    1024 1024   2   proc Dispose       Now you could use the memory variable which is converted to Megabyte

You can use   Process proc   Process GetCurrentProcess      To get the current process and use   proc PrivateMemorySize64    To get the private memory usage  For more information look at this link
