Exceptions

Exception Condition
ArgumentNullException

key is nullNothingnullptra null reference (Nothing in Visual Basic). This exception is thrown when you attempt to reference an instance of the class by using an indexer and the variable you pass in for the key value is nullNothingnullptra null reference (Nothing in Visual Basic).
InvalidOperationException

This exception is thrown when you call the Save method in a wphone app.

Remarks

IsolatedStorageSettings provide a convenient way to store user specific data as key-value pairs in a local IsolatedStorageFile. A typical use is to save settings, such as the number of images to display per page, page layout options, and so on.

User settings can be specific to an application. ApplicationSettings are stored as per-application, per-computer, and per-user settings. Their scope is determined by the full path of the application .xap file.

Version Notes

Windows Phone

On Windows Phone, IsolatedStorageSettings is not thread safe and throws an InvalidOperationException when the Save()()() method is called. However you don’t have to call the Save method on Windows Phone. The data that you store in the IsolatedStorageSettings object is saved automatically.

Examples

The following code example creates an isolated storage settings dictionary, gets a name from the user, stores the name, and then retrieves the name. The name is used in a greeting that is displayed when the page is launched. The code example also enables the user to change, view, and delete the stored name. For information on how to compile and run this example code, see Building examples that have static TextBlock controls for Windows Phone 8.
