1. tasks that do not need to return values

Call. DisplayName = "China Mobile ";
Call. Show ();

You can also enter the phone number in the text box.

2. Short Message task

Mpl. Show ();

Not very nice

Ii. TaskResult returned

1. Save the contact Task

Private void button3_Click (object sender, RoutedEventArgs e)
{
// Save the contact
SavePhoneNumberTask savePhoneNumber = new SavePhoneNumberTask ();
SavePhoneNumber. PhoneNumber = "10086 ";
SavePhoneNumber. Completed + = new EventHandler <TaskEventArgs> (savePhoneNumber_Completed); // Completed binding event
SavePhoneNumber. Show (); // The Show () method is also required.
}

Void savePhoneNumber_Completed (object sender, TaskEventArgs e)
{

If (e. TaskResult = TaskResult. OK) // e event judgment, TaskResult Enumeration
{
MessageBox. Show ("saved successfully ");
}
}

2. photographing Task

{
BitmapImage image = new BitmapImage ();
Image. SetSource (e. ChosenPhoto); // e. ChosenPhoto is a Stream

{
If (e. TaskResult = TaskResult. OK)
{
BitmapImage image = new BitmapImage ();
Image. SetSource (e. ChosenPhoto );
Image1.Source = image;
}
Debug. WriteLine ("FileName:" + e. OriginalFileName + "Length:" + e. OriginalFileName. Length + "bytes ");
}

Effect
