If you have a solution for my issue and want to post an answer, please add some

问题 I have been storing an object which contains a GregorianCalendar object in a db4o database, which works just fine. However, on retrieving the object (after closing and re-opening the database), I cannot seem to access some of the information inside (namely get(GregorianCalendar.MONTH) ).

If you want to access them by their original name, you better save them in the assets folder. Then, you can access them by using the AssetManager : AssetManager am = getResources()

I load the file into an IList with ReadLinesAsync : IList<string> lista1 = await FileIO.ReadLinesAsync(listafile1); Finally I set the ItemsSource of the ListView to this IList: listView1.ItemsSource = lista1; It

问题 I've set up a react web application that's currently listing all "Employees" from a mongodb. I'm now trying to "add" employees to the database through a react frontend form. I've managed to pass the data from the form to the application but I'm unsure of the process I need to go through to actually get that data solidified into an object and stored in the api.
