WinRT information: Error trying to write application data container value

Question

Hi,

I am getting following exception on

ApplicationData.Current.LocalSettings.Values["someke"] = JsonConvert.SerializeObject("list of objects") ;

An exception of type 'System.Exception' occurred in mscorlib.dll but was not handled in user code

WinRT information: Error trying to write application data container value

Additional information: The size of the state manager setting value has exceeded the limit.

Error trying to write application data container value

If there is a handler for this exception, the program may be safely continued.

Plz help if any one can and I will be great thankful to you.

Answer 1

If the object is to large to store in local settings you will need to save the string to a text file in isolated storage

Answer 2

The setting values are allowed to be of few KBs only (I don't remember the limit). You will have to use 1 of the following folder to store the serialized data as file:

ApplicationData.Current.LocalFolder

or

ApplicationData.Current.RoamingFolder

Also, although it's not very clear from the code, I take the risk of saying that "someke" doesn't seem to be representing any kind of user settings.

Answer 3

Hi ,

There's a limit when writing to the localsettings. If I remember correctly you can increase this size but do not expect too much.

I would suggest to write them to a file or use sqlite to store your data.

You can always create a folder of your own , add it to your FutureAccesslist and store in there in a file whatever you want.

Otherwise if you want to make it more structured and correct you can use sqlite.
