The GameOfLife. AdWindow object is in the Survived objects column, which means that the ad window is still alive. After we closed the window, the corresponding object should have been removed from the heap. Nevertheless, something has prevented it from being collected. It's time to start our investigation and find out why our ad window has not been removed!
As mentioned in the How to Get Started with dotMemory tutorial, you should think of your work in dotMemory as of crime investigation. You start your investigation by analyzing a huge list of suspects objects and continuously narrow the list until you find the one that causes the issue. Your chain of reasoning is shown in the so-called Analysis Path on the left side of the dotMemory window. Open the survived GameOfLife. AdWindow instance. To do this, click the number 1 in the Survived objects column next to the GameOfLife.
AdWindow class. As the object exists in both snapshots, dotMemory will prompt you to specify in which snapshot the object should be shown. Of course, we're interested in the last snapshot where the window should have been collected. This will show us the instance "The instance of the AdWindow class that exist both in snapshot 1 and 2". Note that the list of possible views for instances differs from the one of an object set.
For example, the default view for an object instance is Outgoing References that shows the tree of instance's references to other objects. Nevertheless, we're interested not in the objects that are referenced by AdWindow , but only in those that reference it, or, in other words, retain the ad window in memory.
To figure this out, we can simply switch to the Key Retention Paths view. This view shows the graph of retention paths. Note that the view shows not all possible paths , but only those that differ from each other most significantly. This excludes a huge number of very similar retention paths and simplifies the analysis. Hidden categories: AC with 0 elements.
Namespaces Article Talk. Views Read Edit View history. In most situations, the debugger knows the location of the executable files, so you do not have to set the path for this file. However, there are situations when this path is required. For example, kernel-mode small memory dump files do not contain all of the executable files that exist in memory at the time of a stop error that is, a crash. Similarly, user-mode minidump files do not contain the application binaries.
If you set the path of the executable files, the debugger can find these binary files. The debugger's executable image path is a string that consists of multiple directory paths, separated by semicolons. Cache: The result of GetTempPath is usually constant throughout program execution. It is safe to cache it. This eliminates allocations. GetTempPath ; Console. Combine temp, "test. There are 2 properties for separators. These help us develop code that is understandable.
It may be easier to understand the name Path. Next: We examine these 2 properties in the Visual Studio debugger, and see they are the backslash and the forward slash. A program should expect that invalid characters will be encountered. We need to quickly detect invalid path characters.
So: We can use the Path. GetInvalidPathChars methods. Dictionary: We can use the character arrays returned by Path. GetInvalidPathChars with a Dictionary. ToDictionary C program that gets invalid characters using System; using System. Generic; using System. IO; using System. The star is in the Dictionary. NET websites. The Path class does not work well for these paths. For each ASP. From Wikipedia, the free encyclopedia.
The Essentials of Computer Organization and Architecture. All computers have a CPU that can be divided into two pieces. NET doesn't have an abstraction layer over the host OS's file system.
So unless you can build your own for use in custom code, and you need to have 3rd party libraries covered, there are just two workable optilns:.
I went through a similar situation lately, and there is no out of the box solution in. NET for doing that although I used a workaround which was efficient and safe for me. Using Ionic. Zip Nuget package you can create a whole directory with a complex structure as a stream in memory and although it will be created as a zip file, you can extract it as a stream or even send the zip file as a stream.
And here is how to extract a zip file as a stream using Ionic. Learn more. Ask Question. Asked 5 years, 4 months ago.I want to be able to "save" files to that path, manipulate the content or file names, and then save them from that path to a regular file in the file system. I know I can use a temporary file, but I would rather use the memory for both security and performance.
