（1）联系人（Manifest 获取权限）
1）获取联系人
获取联系人的方式有两种
A. ContactPicker
ContactPicker
也就是直接打开一个系统的选择联系人界面，让用户选择，可设置单选或多选：
var contactPicker = new ContactPicker();contactPicker.DesiredFieldsWithContactFieldType.Add(ContactFieldType.PhoneNumber);
//Windows.ApplicationModel.Contacts.Contact contact = await contactPicker.PickContactsAsync();
Windows.ApplicationModel.Contacts.Contact contact = await contactPicker.PickContactAsync();
if( contact != null )
{
MessageDialog dialog = new MessageDialog(string.Format("Phone Number: {0}", contact.Phones.First().Number), contact.DisplayName);
await dialog.ShowAsync();
}
必须设置唯一的一个 ContactFieldType。
B. ContactManager
可通过 ContactManager API 直接搜索某联系人：
ContactStore contactStore = await ContactManager.RequestStoreAsync();
var list = await contactStore.FindContactsAsync(searchTextBox.Text.Trim());
获取的联系人列表为只读的。
2）与联系人联系
可直接向联系人拨打电话、发送短信、发送邮件：
PhoneCallManager.ShowPhoneCallUI("15911111111", "Some");
ChatMessage message = new ChatMessage();
message.Recipients.Add("15911111111");
message.Body = "Test.";
await ChatMessageManager.ShowComposeSmsMessageAsync(message);
EmailMessage email = new EmailMessage();
email.To.Add(new EmailRecipient("[email protected]"));
email.Body = "Test.";
await EmailManager.ShowComposeNewEmailAsync(email);
（2）日历
1）直接打开系统的日历应用
比如打开日历主界面：
await AppointmentManager.ShowTimeFrameAsync(DateTimeOffset.Now, TimeSpan.FromHours(1));
2）API 方式
比如新建一个日历事件：
Appointment appointment = new Appointment();
appointment.Subject = "";
appointment.StartTime = DateTimeOffset.Now;
//...
await AppointmentManager.ShowAddAppointmentAsync(appointment, new Rect());
