July 26, 2012
Gets the dictionary used for passing an application’s state between invocations.
Assembly: Microsoft.Phone (in Microsoft.Phone.dll)
Property Value
Type: System.Collections.Generic.IDictionary<String, Object>Type: IDictionary<TKey, TValue>.
Windows Phone applications are deactivated when the user navigates to another application. When the user returns to the application, by using the Back button or by completing a Launcher or Chooser task, the application is reactivated. An application can store transient application state in the State dictionary in the handler for the Deactivated event. In the Activated event handler, an application can use the values stored in the State dictionary to transient application state. For more information about handling deactivation and reactivation, see Execution Model for Windows Phone.
This method may throw one of the following exceptions.
InvalidOperationException | The State dictionary cannot be modified after the Deactivated event has been handled or before the Activated event has been raised. |
ArgumentOutOfRangeException | Values placed in the State dictionary must be serializable. This exception is only thrown while debugging. At run time, this exception is silently ignored. |
