Windows Phone 二十一、联系人存储

联系人资料是手机上必有的，在最新的 Windows Phone 中开放了相应的 API ，以便于应用程序读写通讯录。

注意：系统没有对整个手机自带的通讯录写入开放权限，每个应用只能管理属于当前应用的联系人。

联系人存储

     <StackPanel>
         <TextBox x:Name="txtName" Header="姓名" InputScope="NameOrPhoneNumber"/>
         <TextBox x:Name="txtTel" Header="电话" InputScope="ChineseHalfWidth"/>
         <TextBox x:Name="txtTel1" Header="电话" InputScope="TelephoneNumber"/>
         <Button x:Name="btnSave" Content="Save" Click="btnSave_Click"/>
         <Button x:Name="btnGet" Content="GET" Click="btnGet_Click"/>
         <Button x:Name="btnPicker" Content="Picker" Click="btnPicker_Click"/>
         <Button x:Name="btnGet2" Content="获取联系人信息2" Click="btnGet2_Click"/>
     </StackPanel>

         private async void btnSave_Click(object sender, RoutedEventArgs e)
         {
             var name = txtName.Text;
             var tel = txtTel.Text;

             // 联系人存储容器
             ContactStore contactStore = await ContactStore.CreateOrOpenAsync(ContactStoreSystemAccessMode.ReadWrite, ContactStoreApplicationAccessMode.ReadOnly);

             // 创建联系人信息对象
             ContactInformation contactInformation = new ContactInformation();
             // 设置联系人信息展示名称
             contactInformation.DisplayName = name;
             // 详细属性
             var contactProps = await contactInformation.GetPropertiesAsync();
             // 详细属性编辑通过字典形式操作，需要记住所有的属性名都有KnownContactProperties点出来
             contactProps.Add(KnownContactProperties.MobileTelephone, tel);

             // 创建一个存储对象将联系人信息存储到存储容器中
             StoredContact storedContact = new StoredContact(contactStore, contactInformation);
             // 保存
             await storedContact.SaveAsync();
         }

         private async void btnGet_Click(object sender, RoutedEventArgs e)
         {
             // 联系人存储容器
             ContactStore contactStore = await ContactStore.CreateOrOpenAsync(ContactStoreSystemAccessMode.ReadWrite, ContactStoreApplicationAccessMode.ReadOnly);

             // 通过联系人存储容器查询联系人列表
             var result = contactStore.CreateContactQuery();

             var count = await result.GetContactCountAsync();

             var list = await result.GetContactsAsync();

             foreach (var item in list)
             {
                 System.Diagnostics.Debug.WriteLine(item.DisplayName);
             }
         }

         private async void btnPicker_Click(object sender, RoutedEventArgs e)
         {
             // 联系人选择器Flyout
             Windows.ApplicationModel.Contacts.ContactPicker contactPicker = new Windows.ApplicationModel.Contacts.ContactPicker();
             // 必须设置以下项
             contactPicker.DesiredFieldsWithContactFieldType.Add(Windows.ApplicationModel.Contacts.ContactFieldType.PhoneNumber);
             // 查询所有选中对象
             var temp = await contactPicker.PickContactsAsync();

         }

两种系统联系人读取的形式

     <Grid>
         <TextBox x:Name="txtSearch"/>
         <Button x:Name="btnSearch" Content="Search" Click="btnSearch_Click"/>
     </Grid>

         private async void btnSearch_Click(object sender, RoutedEventArgs e)
         {
             var contactStore = await Windows.ApplicationModel.Contacts.ContactManager.RequestStoreAsync();
             // 通过联系人存储容器查询联系人列表(全文检索)
             if (string.IsNullOrEmpty(txtSearch.Text))
             {
                 var result = await contactStore.FindContactsAsync();
                 foreach (var item in result)
                 {
                     System.Diagnostics.Debug.WriteLine(item.DisplayName);
                 }
             }
             else
             {
                 var result = await contactStore.FindContactsAsync(txtSearch.Text);
                 foreach (var item in result)
                 {
                     System.Diagnostics.Debug.WriteLine(item.DisplayName);
                 }
             }

             System.Diagnostics.Debug.WriteLine("--------------------------------");
         }
