How to measure the total memory consumption of the current process programmatically in .NET?
Solution 1
Refer to this SO question
Further try this
Process currentProcess = System.Diagnostics.Process.GetCurrentProcess();
long totalBytesOfMemoryUsed = currentProcess.WorkingSet64;
Solution 2
If you only want to measure the increase in say, virtual memory usage, caused by some distinct operations you can use the following pattern:-
GC.Collect();
GC.WaitForPendingFinalizers();
GC.Collect();
var before = System.Diagnostics.Process.GetCurrentProcess().VirtualMemorySize64;
// performs operations here
var after = System.Diagnostics.Process.GetCurrentProcess().VirtualMemorySize64;
This is, of course, assuming that your application in not performing operations on other threads whilst the above operations are running.
You can replace VirtualMemorySize64
with whatever other metric you are interested in. Have a look at the System.Diagnostics.Process
type to see what is available.

PerformanceCounter class -

There are several of them -

Here is the CLR memory counter -

I have found this very useful:
Thread.MemoryBarrier();
var initialMemory = System.GC.GetTotalMemory(true);
// body
var somethingThatConsumesMemory = Enumerable.Range(0, 100000)
.ToArray();
// end
Thread.MemoryBarrier();
var finalMemory = System.GC.GetTotalMemory(true);
var consumption = finalMemory - initialMemory;
