Question

Is there a way to save listArrays in roaming Settings? In js I would do it like that:

var test = [];  
test.push({var1:'somevalue',var2:'someotherstuff'});

but how to save this in:

var appData = Windows.Storage.ApplicationData.current;
var roamingSettings = appData.roamingSettings;

when I try to set the variable like:

roamingSettings.values['myArrayList'] = test;    

I get a typeconflict error. Any ideas how to fix this?

Answer 1

You apparently cannot store an object in the localSettings or roamingSettings values field. However, you can always just stringify and parse your array into JSON to store it instead.

roamingSettings.values['myArrayList'] = JSON.stringify(test); 

and

test = roamingSettings.values['myArrayList'] = JSON.parse(test);

Just remember that the array cannot exceed 8 KB in size for roaming settings. Since you have to stringify it, this includes all the JSON brackets and white space!
