Finding memory leaks in C# application

You need memory profiler to debug such problems. For example:

Also see suggestions from the other question about memory leaks.

Basically, this boils down to finding the objects in memory that stay here while they shouldn't. It can be event handler holding reference to its class or some collection of objects holding references to their parents, and so on. After finding the root cause you may need to restructure your application to get rid of the unnecessary references. This can be as simple as adding forgotten event unsubscription but in non trivial cases might require applying some structural design patterns. This part is very application specific.


Maybe Process class is the right thing you are searching. Use Process myProcess = Process.GetCurrentProcess() to get current process. Then you can use myProcess´s properties like WorkingSet64, PrivateMemorySize64 and so on.

    Valgrind is a powerful memory profiling tool that can help find memory leaks and invalid memory usage.

    Compile the program check_whitespace.c and run valgrind on it to find any leaks it may have (hint: it has at least one). In leak_report.md describe why the memory errors happen, and how to fix them. Actually fix the code. Commit, push, etc. Submit the URL for your repository as instructed elsewhere

    At the end of your program you print or write the contents of your linked list to an logfile. If there are no leaks your linked list should have

    Visual Leak Detector (VLD) is a free, robust, open-source memory leak detection system for Visual C++. When you run your program under the Visual Studio debugger, Visual Leak Detector will output a memory leak report at the end of your debugging session. The leak report includes the full call stack showing how any leaked memory blocks were allocated. Double-click on a line in the call stack to jump to that file and line in the editor window.

    This is shown below: [hello.c:25] **LEAK_ASSIGN** >> string_so_far = string; Memory leaked due to pointer reassignment: string Lost block : 0x0804bd68 thru 0x0804bd6f (8 bytes) string, allocated at hello.c, 15 malloc () (interface) main () hello.c, 15 Stack trace where the error occurred: main () hello.c, 25.

    Memory leak has always been a part of bugs in C code where a programmer allocates memory in run time (in heap) and fails to deallocate it. And

    Even harmless memory leaks might indicate other problems that should be corrected. The Visual Studio debugger and C Run-time Library (CRT) can help you detect and identify memory leaks. Enable memory leak detection. The primary tools for detecting memory leaks are the C/C++ debugger and the C Run-time Library (CRT) debug heap functions.

    % valgrind --tool=memcheck program_name =18515== malloc/free: in use at exit: 0 bytes in 0 blocks. ==18515== malloc/free: 1 allocs, 1 frees, 10 bytes allocated. ==18515== For a detailed leak analysis, rerun with: --leak-check=yes If you have a memory leak, then the number of allocs and the number of frees will differ (you can't use one free to release the memory belonging to more than one alloc).

    The main idea of this article is to describe an approach that gives an ability to find memory leaks in C code on macOS.

    CMemLeak is a small tool for detecting memory leaks in C programs. It does not replace and is not as good as the commercially available tools.
