Public NotInheritable Class PhoneNumberChooserTask _ Inherits ChooserBase(Of PhoneNumberResult)
public sealed class PhoneNumberChooserTask : ChooserBase<PhoneNumberResult>
The PhoneNumberChooserTask type exposes the following members.
|PhoneNumberChooserTask||Initializes a new instance of the PhoneNumberChooserTask class.|
|TaskEventArgs||The EventArgs for the Completed event. (Inherited from ChooserBase<(Of <(TTaskEventArgs>)>).)|
|Equals(Object)||Determines whether the specified Object is equal to the current Object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)|
|FireCompleted||Raises the Completed event. (Inherited from ChooserBase<(Of <(TTaskEventArgs>)>).)|
|GetHashCode||Serves as a hash function for a particular type. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|Show||Shows the Contacts application. (Overrides ChooserBase<(Of <(TTaskEventArgs>)>)..::.Show()()().)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
|Completed||Occurs when a Chooser task is completed. (Inherited from ChooserBase<(Of <(TTaskEventArgs>)>).)|
Launch the Contacts application by calling the Show method of the PhoneNumberChooserTask object. Obtain the result of the chooser operation by handling the Completed event.
On Windows Phone, your application may be deactivated while the Contacts application is in the foreground. To ensure that your application receives the result of the PhoneNumberChooserTask, the object must be declared with class scope within the PhoneApplicationPage class and you must call the chooser constructor and assign the Completed event delegate within the page’s constructor. For more information about how to handle the activation and deactivation of your application, seeApp activation and deactivation for Windows Phone 8.
