How do i get memory usage of specific application just like it show in the windows task manager?

Question

public static void getallmemoryusage(string processName)
{
    Process[] pprocessName = Process.GetProcessesByName(processName);//.GetCurrentProcess().ProcessName;
    var counter = new PerformanceCounter("Process", "Working Set - Private", processName);
    privateMemeory = string.Format("Private memory: {0}k", counter.NextValue() / 1024);
}

Some problems here:

1. I have a variable Process[] pprocessName but i never use it.

2. The it is now i'm getting a value that is not the same one in the task manager.

In the task manager i see 192.6MB in my program i see 197232. Now i started playing the game use the application(process) now in task manager it show: 219.0MB in my program 224304.

Why it's now the same values and what should i do with the Process[] pprocessName variable ? Also how do i show the percentage/s for the application(process) like it show it in task manager ?

I want that this method will return the same value of memory usage and same percentage value like in the task manager.

Answer 1

Yes. You can get the physical amount of memory occupied by each through the WorkingSet64 property of th Process class.

MSDN says:

The amount of physical memory, in bytes, allocated for the associated process.

In your case pprocessName is the array of processes with the name "processName" So you can do:

foreach(var process in pprocessName)
{
  var memoryBytes = process.WorkingSet64;
  //...
}
