Find Memory usage and CPU usage

In this article author explain about how to Find Memory usage and CPU usage

This sample code shows to find the RAM (memory) usage and CPU usage of a computer. This method is very usefull in order to monitor the system and particulary the amount of the available RAM in MB (MegaBytes) and the cpu usage in percents.

// Page Level declaration
protected System.Diagnostics.PerformanceCounter cpuCounter;
protected System.Diagnostics.PerformanceCounter ramCounter;

// Put into page load
cpuCounter = new System.Diagnostics.PerformanceCounter();
cpuCounter.CategoryName = "Processor";
cpuCounter.CounterName = "% Processor Time";
cpuCounter.InstanceName = "_Total";
ramCounter = new System.Diagnostics.PerformanceCounter("Memory", "Available MBytes");

// Call this method every time you need to know the current cpu usage.
public string getCurrentCpuUsage()
return cpuCounter.NextValue()+"%";

// Call this method every time you need to get the amount of the available RAM in Mb
public string getAvailableRAM()
return ramCounter.NextValue() + "Mb";

// Put this code into button click event
textBox3.Text = getCurrentCpuUsage();
textBox4.Text = getAvailableRAM();

Thanks, usefull snippet. Can this be used to measure the memory usage by the applications running. What I mean is lets say I develop myapp.exe, while it is running, I display the RAM used by my application in the interface in C#
