Windows Phone 8.1 contacts vs. calendars

(1) Contact person (Manifest get permission)

1) Get Contacts

There are two ways to get a contact

A. Contactpicker

Contactpicker is the direct opening of a system to select the contact interface, let the user choose, you can set a single or multiple selection:

varContactpicker =NewContactpicker (); ContactPicker.DesiredFieldsWithContactFieldType.Add (contactfieldtype.phonenumber);//Windows.ApplicationModel.Contacts.Contact contact = await contactpicker.pickcontactsasync ();Windows.ApplicationModel.Contacts.Contact contact =awaitContactpicker.pickcontactasync ();if(Contact! =NULL) {Messagedialog dialog=NewMessagedialog (string. Format ("Phone number: {0}", contact. Phones.first (). Number), contact.    DisplayName); awaitdialog. Showasync ();}

A unique contactfieldtype must be set.

B. Contactmanager

You can search for a contact directly via the Contactmanager API:

await Contactmanager.requeststoreasync (); var await Contactstore.findcontactsasync (SearchTextBox.Text.Trim ());

Gets the list of contacts as read-only.

2) Contact the contact person

You can make a call directly to a contact, send a text message, send an email:

Phonecallmanager.showphonecallui ("15911111111","Some"); Chatmessage message=Newchatmessage (); message. Recipients.add ("15911111111"); message. Body="Test.";awaitchatmessagemanager.showcomposesmsmessageasync (message); Emailmessage Email=Newemailmessage (); email. To.add (NewEmailrecipient ("[email protected]") ; email. Body="Test.";awaitEmailmanager.showcomposenewemailasync (email);
