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("--------------------------------");
        }
