How to measure memory usage with C# (as we can do in Java)? [duplicate]

Answer 1

Heres one way, using the GC:

    public void Test()
    {
        long kbAtExecution = GC.GetTotalMemory(false) / 1024;

        // do stuff that uses memory here 

        long kbAfter1 = GC.GetTotalMemory(false) / 1024;
        long kbAfter2 = GC.GetTotalMemory(true) / 1024;

        Console.WriteLine(kbAtExecution + " Started with this kb.");
        Console.WriteLine(kbAfter1 + " After the test.");
        Console.WriteLine(kbAfter1 - kbAtExecution + " Amt. Added.");
        Console.WriteLine(kbAfter2 + " Amt. After Collection");
        Console.WriteLine(kbAfter2 - kbAfter1 + " Amt. Collected by GC.");         
    }

Or alternatively using System.Diagnostics.PerformanceCounter to get working set info:

PerformanceCounter performanceCounter = new PerformanceCounter();

performanceCounter.CategoryName = "Process";

performanceCounter.CounterName = "Working Set";

performanceCounter.InstanceName = Process.GetCurrentProcess().ProcessName;

Console.WriteLine(((uint)performanceCounter.NextValue()/1024).ToString("N0"));

The GC static class provides all this type of information.

Your probably after GC.GetTotalMemory().

EDIT:

I beleive that attempts to workout your memory footprint based on currently rooted objects. IF you want the total size allocated for the process (i.e. including the free buffer) use the Process class. e.g.:

Process.GetCurrentProcess().WorkingSet64;
