- Webサービス「http://service.mydomain.com/MobileService.asmx」を作成しました
- Windowsモバイルアプリケーションを作成しました
- このWebサービスへの参照を追加しました
- コーディングを開始してWP7アプリケーションを終了し、サービスを展開しました
- 次に、IIS 7.5を使用して匿名認証を無効にし、基本認証を使用してWebサービスを保護しました。
- 基本認証を使用した後、サービスに新しい参照を追加し、VS 2010が認証について質問した後、ユーザー名とパスワードを使用しました
その後、新しいサービスを使おうとすると、例外が発生しました。

これが私のWebサービスに接続しようとしている方法です：
ParsingHelper.csで：
using System;
using System.Text.RegularExpressions;
using System.Xml.Serialization;
using System.Collections.ObjectModel;
namespace MyWP7App
{
[XmlRoot("root")]
public class Categories
{
[XmlArray("Categories")]
[XmlArrayItem("Category")]
public ObservableCollection<Category> Collection { get; set; }
}
}
public class Category
{
[XmlAttribute("ID")]
public int ID { get; set; }
[XmlAttribute("SubCategories")]
public int SubCategoriesCount { get; set; }
[XmlElement("Name")]
public string Name { get; set; }
[XmlArray("SubCategories")]
[XmlArrayItem("SubCategory")]
public ObservableCollection<SubCategory> Collection { get; set; }
}
MyPage.xaml.cs内：
using System;
using System.Collections.ObjectModel;
using System.Linq;
using System.Windows;
using System.Windows.Controls;
using System.Xml.Serialization;
using Microsoft.Phone.Controls;
using System.Xml.Linq;
namespace MyWP7App
{
public partial class CategoriesPage : PhoneApplicationPage

public ObservableCollection<Category> ItemsSource

{
this.itemsSource = value;
}
}
private static MyService.MobileServiceSoapClient Service = null;
public PanoramaMainPage()
{
InitializeComponent();
if (null == ItemsSource)
GetCategories();
else
imtListBox.ItemsSource = this.ItemsSource;
}
private void GetCategories()
{
Service = new MyService.MobileServiceSoapClient();
// I tried to do the following when the service is secure, but I had the same error:
// Service.ClientCredentials.UserName.UserName = "Username";

Service.GetCategoriesCompleted += new EventHandler<MyService.GetCategoriesCompletedEventArgs>(Service_GetCategoriesCompleted);
Service.GetCategoriesAsync();
}
void Service_GetCategoriesCompleted(object sender, MyService.GetCategoriesCompletedEventArgs e)
{
try
{
if (e.Result == null || e.Error != null)
{
MessageBox.Show("There was an error downloading the XML-file!");
}
if (!e.Cancelled)
{
XmlSerializer serializer = new XmlSerializer(typeof(Categories));
XDocument document = XDocument.Parse("<root>" + e.Result.ToString() + "</root>");
Categories arts = new Categories();
arts = (Categories)serializer.Deserialize(document.CreateReader());
this.ItemsSourceListBox = arts.Collection;

}
}
catch (Exception ex)
