  1. 我创建了一个网络服务“http://service.mydomain.com/MobileService.asmx”
  2. 我创建了一个 Windows 移动应用程序
  3. 我添加了对此 Web 服务的引用
  4. 我开始编码并完成了 WP7 应用程序并部署了 we 服务
  5. 然后我使用 IIS 7.5 禁用匿名身份验证并使用基本身份验证来保护我的 Web 服务。
  6. 使用基本身份验证后，我添加了对我的服务的新引用，VS 2010 询问身份验证，我使用了我的用户名和密码

  7. 然后，当我尝试使用新服务时，我遇到了异常。

    Reference.cs 上的错误：

    公共 System.IAsyncResult BeginGetArticle(MyWP7App.MyService.GetArticleRequest 请求，System.AsyncCallback 回调，对象 asyncState) { object[] _args = new object[1]; _args[0] = 请求；System.IAsyncResult _result = base.BeginInvoke("GetArticle", _args, callback, asyncState); 返回_结果；}


CommunicationException：{“远程服务器返回错误：NotFound。”}

这就是我尝试连接到我的网络服务的方式：
在 ParsingHelper.cs 中： 

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; }
    }


在 MyPage.xaml.cs 中： 

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
        {
        private ObservableCollection<Category> itemsSource;
        public ObservableCollection<Category> ItemsSource
        {
            get
            {
                return this.itemsSource;
            }
            set
            {
                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.ClientCredentials.UserName.Password = "Password";

            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;
                    imtListBox.ItemsSource = this.Items1Source;
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
            Service.Abort();
        }
    }

看看这篇文章 http://msdn.microsoft.com/en-us/library/ff637320(VS.96).aspx

这篇文章详细介绍了如何传递用户名/密码。这是页面中的一个片段

using (OperationContextScope contextScope = new OperationContextScope(svc.InnerChannel))
{
    byte[] bc = System.Text.Encoding.UTF8.GetBytes(@"username" + ":" + "password"); // the string passed after basic:
    HttpRequestMessageProperty httpProps = new HttpRequestMessageProperty();
    httpProps.Headers[HttpRequestHeader.Authorization] = "Basic " + Convert.ToBase64String(bc);
    OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] = httpProps;
    // call the service.
}
