c# - 在 Windows Phone 8 c# 中合并相同的联系人与不同的联系人详细信息

Question

在我的 Windows Phone 应用程序中，我正在将所有联系人添加到我的应用程序中，如下所示:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Navigation;
using Microsoft.Phone.Controls;
using Microsoft.Phone.Shell;
using GetContacts.Resources;
using Microsoft.Phone.UserData;

namespace GetContacts
{
    public partial class MainPage : PhoneApplicationPage
    {
        // Constructor
        public MainPage()
        {
            InitializeComponent();

            // Sample code to localize the ApplicationBar
            //BuildLocalizedApplicationBar();
        }

        private void MergeContacts_Click(object sender, RoutedEventArgs e)
        {
            Contacts cons = new Contacts();
            cons.SearchCompleted += new EventHandler<ContactsSearchEventArgs>(Contacts_SearchCompleted1);

            cons.SearchAsync(String.Empty, FilterKind.None, "Contacts Test #1");
        }

        private void Contacts_SearchCompleted1(object sender, ContactsSearchEventArgs e)
        {
            // MessageBox.Show(e.Results.Count().ToString());
            try
            {
               ContactResultsData.DataContext = e.Results;
            }
            catch (System.Exception)
            {
                //No results
            }

            if (ContactResultsData.Items.Any())
            {
                ContactResultsLabel.Text = "results";
            }
            else
            {
                ContactResultsLabel.Text = "no results";
            }
        }


    }
}

它工作正常，让我获得所有联系人列表，下面是我的 xaml 代码:

 <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
            <StackPanel>
                <TextBlock Name="ContactResultsLabel" Text="results are loading..." Style="{StaticResource PhoneTextLargeStyle}" TextWrapping="Wrap" />

                <ListBox Name="ContactResultsData" ItemsSource="{Binding}" Height="200" Margin="24,0,0,0" >
                    <ListBox.ItemTemplate>
                        <DataTemplate>
                            <TextBlock Name="ContactResults" Text="{Binding Path=DisplayName, Mode=OneWay}" />
                        </DataTemplate>
                    </ListBox.ItemTemplate>
                </ListBox>
            </StackPanel>
            <Button x:Name="ButtonContacts"
                    Content="Get All Contacts"
                    FontSize="15"
                    Width="200"
                    Height="70"
                    Background="AliceBlue"
                    Foreground="Blue"
                    HorizontalAlignment="Left"
                    Click="ButtonContacts_Click"></Button>
            <Button x:Name="MergeContacts"
                    Content="Merge Contacts"
                    FontSize="15"
                    Width="200"
                    Height="70"
                    Background="AliceBlue"
                    Foreground="Blue"
                    HorizontalAlignment="Right"
                    Click="MergeContacts_Click"></Button>
        </Grid>

但是当我创建与不同的联系人详细信息，如联系人姓名 Alan 联系人详细信息“手机号码 1234567890”，然后创建另一个同名联系人 Alan 和联系人详细信息电话号码 923451234567它显示了两个同名联系人 Alan，我想将此联系人详细信息与一个联系人姓名 Alan 合并。

请建议我，等待您的回复。谢谢。

这是一个例子，我从一个 xml 文件中读取并附加到 wp8 中的 tihe 联系人类中

你可以通过一些修改来做同样的事情....

您需要根据您的要求稍微修改一下 LinQ 查询...

//按钮点击事件从xml文件中读取联系人写入联系人

    private void adcnts_Click(object sender, RoutedEventArgs e)
    {
        aaaaaa();
        using (IsolatedStorageFile istf = IsolatedStorageFile.GetUserStoreForApplication())
        {
            using (IsolatedStorageFileStream istfs = istf.OpenFile("MyContacts.xml", FileMode.Open))
            {
                XDocument doc = XDocument.Load(istfs);
                var query = from d in doc.Root.Descendants("Contacts")
                            select new
                            {
                                firtName = d.Element("name").Value,
                                mobilePhone = d.Element("phone").Value
                            };
                //Global qq = new Global();

                foreach (var po in query)
                {
                    //qq.cnts.Add(new Contactss()
                    //{
                    //    name = po.firtName,
                    //    number = po.mobilePhone
                    //});

                    saveContactTask.FirstName = po.firtName;
                    saveContactTask.MobilePhone = po.mobilePhone;
                    saveContactTask.Show();
                }
            }
        }
       // saveContactTask.Show();



    }
    public void aaaaaa()
    {

        saveContactTask = new SaveContactTask();
        saveContactTask.Completed += new EventHandler<SaveContactResult>(saveContactTask_Completed);
    }

    private void saveContactTask_Completed(object sender, SaveContactResult e)
    {
        switch (e.TaskResult)
        {
          // Logic for when the contact was saved successfully
            case TaskResult.OK:
               MessageBox.Show("Contact saved.");
                break;

         //Logic for when the task was cancelled by the user
            case TaskResult.Cancel:
                MessageBox.Show("Save cancelled.");
                break;

            //Logic for when the contact could not be saved
            case TaskResult.None:
                MessageBox.Show("Contact could not be saved.");
                break;
        }
    }
