檢索聯繫人號碼C＃WP8

Question

編輯名單：新的問題 - 爲清楚起見&新代碼中看到Selecting contacts in windows phone 8

誰downvoted，非常感謝。非常有建設性。

感謝MSDN和這裏的支持，得到了以下代碼工作，它填充聯繫人列表並允許用戶在將它們保存到List對象之前選擇多個聯繫人。

但是，我現在想知道如何檢索與檢索到的每個名稱關聯的聯繫號碼。我試過後續的搜索，但我覺得我做錯了，每次只是打破了代碼。

任何幫助將不勝感激，謝謝。

 private void showContacts(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()); 
      try 
      { 
       //Bind the results to the user interface. 
       ContactResultsData.DataContext = e.Results; 
      } 
      catch (System.Exception) 
      { 
       //No results 
      } 

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

     public void saveContacts(object sender, RoutedEventArgs e) 
     { 
      String strItem; 

      List<string> listOfNames = new List<string>(); 

      foreach (Object selecteditem in ContactResultsData.SelectedItems) 
      { 
       //MessageBox.Show(selecteditem.ToString()); 
       strItem = selecteditem as String; 
       ContactResultsLabel.Text = strItem; 

       listOfNames.Add(strItem); 

       //System.Diagnostics.Debug.WriteLine(strItem); 
       //MessageBox.Show("Saving " + strItem); 
      } 
     } 
    } 
} 

Answer 1

使用VAR而不是對象

我理解你的要求，但我不明白你的代碼，反正

我僅舉像如果ContactResultsData.SelectedItems一直數據庫值的鍵，然後再嘗試這種方式

foreach (var selecteditem in ContactResultsData.SelectedItems) 
      { 
       //MessageBox.Show(selecteditem.ToString()); 

       ContactResultsLabel.Text = selecteditem.Name;//The Name is ContactResultsData.SelectedItems return Column Field name 
       ContactNumberResult.Text = selecteditem.Number;//The Name is ContactResultsData.SelectedItems return Column Field name 

       listOfNames.Add(strItem); 

       //System.Diagnostics.Debug.WriteLine(strItem); 
       //MessageBox.Show("Saving " + strItem); 
      } 

Answer 2

下面這個例子是對Group Contacts應用程序實現的：

XAML：

<HyperlinkButton x:Name="CompanyButton" Content="{Binding ElementName=grid, Path=DataContext.SelectedContact.JobInfo, Converter={StaticResource WorkToTextConverter}}" Visibility="{Binding ElementName=grid, Path=DataContext.SelectedContact.JobInfo, Converter={StaticResource WorkToVisibilityConverter}}" IsEnabled="{Binding ElementName=grid, Path=DataContext.SelectedContact.Phones, Converter={StaticResource WorkPhoneExistsConverter}}"/> 
<HyperlinkButton x:Name="MobileButton" Content="Mobile" Visibility="{Binding ElementName=grid, Path=DataContext.SelectedContact.Phones, Converter={StaticResource MobileToVisibilityConverter}}"/> 
<HyperlinkButton x:Name="MessageButton" Content="Message" Visibility="{Binding ElementName=grid, Path=DataContext.SelectedContact.Phones, Converter={StaticResource MobileToVisibilityConverter}}"/> 
<HyperlinkButton x:Name="EmailButton" Content="Email"  Visibility="{Binding ElementName=grid, Path=DataContext.SelectedContact.Emails, Converter={StaticResource EmailsToVisibilityConverter}}" /> 

。 。

代碼：

private void Call(object e) 
{ 
    ContactPhone phone = null; 

    var kind = e as string; 

    switch (kind) 
    { 
     case "Mobile": 
      { 
       phone = SelectedContact.Phones.Where(p => p.Kind == ContactPhoneKind.Mobile).FirstOrDefault(); 
       break; 
      } 

     case "Work": 
      { 
       phone = SelectedContact.Phones.Where(p => p.Kind == ContactPhoneKind.Work).FirstOrDefault(); 
       break; 
      } 
}
