This snippet will list all the filenames of a zip archive. The filenames are relative to the zip root. using (FileStream fs = new FileStream("archive.zip", FileMode.Open)) using (ZipArchive archive = new ZipArchive(fs, ZipArchiveMode.Read)) { for (int i = 0; i < archive.Entries....

Extracting all the files into a directory is very easy: using (FileStream fs = new FileStream("archive.zip", FileMode.Open)) using (ZipArchive archive = new ZipArchive(fs, ZipArchiveMode.Read)) { archive.ExtractToDirectory(AppDomain.CurrentDomain.BaseDirectory); } When the file...

To update a ZIP file, the file has to be opened with ZipArchiveMode.Update instead. using (FileStream fs = new FileStream("archive.zip", FileMode.Open)) using (ZipArchive archive = new ZipArchive(fs, ZipArchiveMode.Update)) { // Add file to root archive.CreateEntryFromFile(&qu...

The operators <, <=, > and >= are binary operators for comparing numeric types. The meaning of the operators is as you would expect. For example, if a and b are declared as any of byte, short, char, int, long, float, double or the corresponding boxed types: - `a < b` tests if the v...

Detailed instructions on getting graph-theory set up or installed.

This example is strictly a workaround since, currently there is no way to disable a behaviour known as ShiftMode. Create a function as such. public static void disableMenuShiftMode(BottomNavigationView view) { BottomNavigationMenuView menuView = (BottomNavigationMenuView) view.getChildAt(0); ...

If you want to use Swift3.0 or Bitcode you can add this code in your podfile. post_install do |installer| installer.pods_project.targets.each do |target| target.build_configurations.each do |config| config.build_settings['ENABLE_BITCODE'] = 'YES' config.build_settings['SWIFT...

For this example we will test the sum method of a simple calculator. In this example we will test the application: ApplicationToTest. This one has a class called Calc. This class has a method Sum(). The method Sum() looks like this: public void Sum(int a, int b) { return a + b; } The un...

Java Singleton Pattern To implement Singleton pattern, we have different approaches but all of them have following common concepts. Private constructor to restrict instantiation of the class from other classes. Private static variable of the same class that is the only instance of the class. P...

In order to set the pagination style for the entire project, you need to set the DEFAULT_PAGINATION_CLASS and PAGE_SIZE on the project settings. To do so, go to settings.py and on the REST_FRAMEWORK variable, add the following: REST_FRAMEWORK = { 'DEFAULT_PAGINATION_CLASS': 'rest_fr...

Decoding the chunks of a PNG file demonstrates Okio in practice. private static final ByteString PNG_HEADER = ByteString.decodeHex("89504e470d0a1a0a"); public void decodePng(InputStream in) throws IOException { try (BufferedSource pngSource = Okio.buffer(Okio.source(in))) { Byt...

ByteStrings and Buffers Okio is built around two types that pack a lot of capability into a straightforward API: ByteString is an immutable sequence of bytes. For character data, String is fundamental. ByteString is String's long-lost brother, making it easy to treat binary data as a value. This c...
