如何使用silverlight和c＃以编程方式阅读Windows Phone 7中的联系人？

Answer 1

现在，您只能通过EmailAddressChooserTask API一次访问一个联系人。没有办法阅读整个联系人列表。

Answer 2

如果您使用的是Windows Phone 7.0，则一次只能阅读一个联系人。如此使用EmailAddressChooserTask或PhoneNumberChooserTask，您可以使用EmailAddressChooserTask执行相同操作：

private PhoneNumberChooseTask myPhoneChooserTask;

public MainPage()
{
   InitializeComponent();
   myPhoneChooserTask = new PhoneNumberChooseTask ();
   myPhoneChooserTask.Completed += (o, e) => 
   {
      if (e.TaskResult == TaskResult.OK)
         //Here means the phone is chosen successfully. you can access the phone number with e.PhoneNumber
      else
         //Here means the phone is not chosen
   }
   myPhoneChooserTask.Show(); //Show contact list for choosing
}

但是，使用Windows OS 7.1，您可以使用联系人搜索读取所有联系人，如下所示使用空字符串。取自http://msdn.microsoft.com/en-us/library/hh286416(v=vs.92).aspx

private void ButtonContacts_Click(object sender, RoutedEventArgs e)
{
    Contacts cons = new Contacts();

    //Identify the method that runs after the asynchronous search completes.
    cons.SearchCompleted += new EventHandler<ContactsSearchEventArgs>(Contacts_SearchCompleted);

    //Start the asynchronous search.
    cons.SearchAsync(String.Empty, FilterKind.None, "Contacts Test #1");
}

void Contacts_SearchCompleted(object sender, ContactsSearchEventArgs e)
{
    //Do something with the results.
    MessageBox.Show(e.Results.Count().ToString());
}

祝你好运！
