Array in localsettings

Question

Hi, I'm making an app where I need an array of information to persist across all sessions. I assumed the way to do this was to store it in local settings, and get it out of local settings when the app launches. However, it is apparently not possible to store an array or an object in local settings:

Windows.Storage.ApplicationData.current.localSettings.values["key1"] = "A string";                  // this line executes fine
Windows.Storage.ApplicationData.current.localSettings.values["key2"] = ["a", "b", "c"];             // this one breaks
Windows.Storage.ApplicationData.current.localSettings.values["key3"] = { info: "a", number: 2 };    // this one also breaks

Is there a different way I should be doing this? I assume this is by design and not a bug

Answer 1

That's the beauty of JS

Windows.Storage.ApplicationData.current.localSettings.values["key1"] = "A string";
Windows.Storage.ApplicationData.current.localSettings.values["key2"] = JSON.stringify(["a", "b", "c"]);
Windows.Storage.ApplicationData.current.localSettings.values["key3"] = JSON.stringify({ info: "a", number: 2 });

// and then

var value1 = Windows.Storage.ApplicationData.current.localSettings.values["key1"];
var value2 = JSON.parse(Windows.Storage.ApplicationData.current.localSettings.values["key2"]);
var value3 = JSON.parse(Windows.Storage.ApplicationData.current.localSettings.values["key3"]);

Okay, that was easy enough. Thanks!
