![]() There, you're actually requesting the registered implementation of the IDataService interface, rather than instantiating a concrete class. Var service = ActivatorUtilities.GetServiceOrCreateInstance(host.Services) In this example, of course, it doesn't really matter because you're doing the registration and instantiation in code and even in the same class, but if you were to move to something like runtime configuration of what implementation provides the IDataService implementation then this would be the wrong way to go.Īfter a bit of digging around I found that I could do the following which I think might be a better demonstration for this example: There you're tying that instance creation to a concrete class, effectively nullifying the benefit of DI. The best use of Termux is from the command line, it is possible to do graphical apps with Termux, but not recommended due to the difficulty, CLICK HERE for more. I'm just a bit confused why you're using var service = ActivatorUtilities.CreateInstance(host.Services) when you've already registered the DataService class. It really helped me get started with DI in. To pass arguments to the console application when testing the application logic the arguments can be written into the debug section of the project properties as shown below.Thanks for a great walkthrough. If the arguments were not enclosed by double quotes each word would be considered an argument. “This is parameter 1” “This is parameter 2” ![]() For example the following would be interpreted as two arguments or parameter values: The delimiter for command line separating arguments or parameter values is a single space. When run the example above will list out the parameters you have provided to the command window. ![]() Usually you determine whether arguments exist by testing the Length property as in the example above. ![]() Keep in mind, because Android Studio is based on IntelliJ IDEA, you can find additional shortcuts in the IntelliJ IDEA keymap reference documentation. Table 1 shows the default keyboard shortcuts by operating system. The parameter of the Main method is a String array that represents the command-line arguments. Android Studio includes keyboard shortcuts for many common actions. When the application is started, the Main method is the first method that is invoked. The Main method is the entry point of a C# application. Keep the console window open after the program has run. for ( int i = 0 i < args.Length i++)Ĭonsole.Write(args + Environment.NewLine) Loop through array to list args parameters. Display message to user to provide parameters. ![]()
