Exceptions

Exception Condition
ArgumentNullException

key is nulla 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 nulla null reference (Nothing in Visual Basic).

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 or shared across applications in the same domain. 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. SiteSettings are stored as per-domain, per-computer, and per-user settings. Their scope is determined by the sub-domain that hosts the application .xap file. For example, an application at https://www.contoso.com/site1/application.xap will have different ApplicationSettings than an application at https://www.contoso.com/site2/application.xap. However, both applications will share the same SiteSettings because they are hosted on the same sub-domain.

NoteNote:

The .xap files are not accessed directly; they are hosted within a Web page.

Like all data stored in isolated storage using Silverlight, IsolatedStorageSettings are stored locally on the user's computer. In Windows 7, the information is stored in the AppData\LocalLow directory. For other operating system versions, including those on the Apple Macintosh, information is stored in the AppData\Local directory. Values stored in isolated storage are stored locally and are not available for roaming.

NoteNote:

If you have multiple instances of an out-of-browser application running on the same computer and you use IsolatedStorageSettings, you may experience unexpected behavior when reading and saving settings. If this is a scenario for your application, consider using the IsolatedStorageFile APIs instead of IsolatedStorageSettings.

Platform Notes

Silverlight for Windows Phone Silverlight for Windows Phone

On Silverlight for Windows Phone, IsolatedStorageSettings is not thread safe and throws an IsolatedStorageException when Save() is called.

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.
