Question

从Silverlight 2.0控件到通过MyWebServiceNameEventArgs返回的WebService的调用未返回包含List＆lt;＆gt;聚集。例如，我有一个Person类，它有一个List和List。当我跟踪呼叫时，我看到该人员列表已正确填充。但是，当它通过MyWebServiceNameEventArgs到达时，列表为空。正确返回FirstName，DOB等简单类型。

我是否需要做一些事情才能返回封闭的聚合？

这是我的代码：

private void btnGetPerson_Click(object sender, RoutedEventArgs e)
{
  var proxy = new TutorWCFServicesClient();
  proxy.GetPersonWithPersonKeyOfCompleted += new EventHandler<GetPersonWithPersonKeyOfCompletedEventArgs>(proxy_GetPersonWithPersonKeyOfCompleted);
  var perID = 29; // testing
  proxy.GetPersonWithPersonKeyOfAsync(perID);
}

void proxy_GetPersonWithPersonKeyOfCompleted(object sender, GetPersonWithPersonKeyOfCompletedEventArgs e)
{
  var per = e.Result;
  if (per != null)
  {
    FirstName.Text = per.FirstName;
    LastName.Text = per.LastName;
    if (per.Phones != null)
    {
      var hPhone = (from phone in per.Phones where phone.PhoneType.ToLower() == "home" select phone).FirstOrDefault();
      var cPhone = (from phone in per.Phones where phone.PhoneType.ToLower() == "cell" select phone).FirstOrDefault();
      var wPhone = (from phone in per.Phones where phone.PhoneType.ToLower() == "work" select phone).FirstOrDefault();

      if (hPhone != null)
      {
        PhoneHome.Text = string.Format("({0}) {1}-{2}", hPhone.AreaCode, hPhone.Exchange, hPhone.Number);
      }
      if (cPhone != null)
      {
        PhoneCell.Text = string.Format("({0}) {1}-{2}", cPhone.AreaCode, cPhone.Exchange, cPhone.Number);
      }
      if (wPhone != null)
      {
        PhoneSchool.Text = string.Format("({0}) {1}-{2}", wPhone.AreaCode, wPhone.Exchange, wPhone.Number);
      }
    }
  }
  else
  {
    FirstName.Text = "Not Found";
  }
}

哑巴错误，我忘了刷新Silverlight应用程序中的ServiceReference。

从Silverlight Async调用返回的对象将丢失其包含的聚合
