在模擬器中工作在調試和不調試，但只在設備上調試

Question

我正在開發WP7的應用程序，但我碰到了一個我以前沒見過的問題。當我在仿真器中構建並運行它時，它在調試和無調試（ctrl-F5）中都應如此。但在Windows設備上，它只能用於調試（F5）。當我在設備上運行它時沒有進行調試（ctrl-F5），應用程序啓動，但是當我點擊按鈕時，它只是退出應用程序。在按鈕單擊中，我加載一個xml文件。 xml文件設置爲構建操作「內容」，複製到輸出「不要複製」。難道我做錯了什麼？我想知道如果在XAML文件下面的代碼加載beeing有什麼做的錯誤：

而且MainViewModel：

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Net; 
using System.Windows; 
using System.Windows.Controls; 
using System.Windows.Documents; 
using System.Windows.Input; 
using System.Windows.Media; 
using System.Windows.Media.Animation; 
using System.Windows.Shapes; 
using Microsoft.Phone.Controls; 
using appname.Helpers; 

namespace appname 
{ 
    public class MainViewModel 
    { 
     public MainViewModel() 
     { 
      App app = Application.Current as App; 

      XmlHelper xmlHelper = new XmlHelper(); 
      app.persons = xmlHelper.GetPersons(app.gender); 
      List<Person> persons = app.persons; 


      this.Persons = new LongListCollection<Person,char>(persons, person => person.Name[0]); 
     } 

     public LongListCollection<Person, char> Persons 
     { 
      get; 
      private set; 
     } 
    } 
} 

編輯 代碼爲xml文件讀取：

public List<Person> GetPersons(string gender) 
    { 
     string xmlPath = ""; 
     if (gender == "Boys") 
      xmlPath = @"Resources/Boys/Xml/Names.xml"; 
     else if(gender == "Girls") 
      xmlPath = @"Resources/Girls/Xml/Names.xml"; 

     //Uri uri = new Uri(xmlPath, UriKind.Relative); 
     StreamResourceInfo sm = Application.GetResourceStream(new Uri(xmlPath, UriKind.Relative)); 
     System.Xml.XmlReader xr = System.Xml.XmlReader.Create(sm.Stream); 

     XDocument data = XDocument.Load(xr); 



     return (from c in data.Descendants("Person") 
       orderby c.Attribute("Name") 
       select new Person() 
       { 
        Name = c.Element("Name").Value, 
        Description = c.Element("Description").Value, 
        ... 
        HasGraph = c.Element("HasGraph").Value 
       }).ToList(); 
    }

天哪

我想我的手機上啓動另一個應用程序，它也退出。所以，我重新啓動了手機（以爲我昨天就這麼做過了），而且它工作正常！我很抱歉浪費你的時間！

問候一個尷尬的傻瓜！

沒有錯，你每說發佈的代碼。我們需要查看您的XmlHelper課程的代碼，以提供詳細信息。

但是，我懷疑你是以錯誤的方式處理資源管理。另外，我建議你嘗試將代碼包裝在try/catch中，然後使用帶有異常消息的MessageBox.Show。

至少應該確保碰撞是否與異常相關。

public MainViewModel() 
{ 
    try 
    { 
     App app = Application.Current as App; 

     XmlHelper xmlHelper = new XmlHelper(); 
     app.persons = xmlHelper.GetPersons(app.gender); 
     List<Person> persons = app.persons; 


     this.Persons = new LongListCollection<Person,char>(persons, person => person.Name[0]); 
    } 
    catch (Exception e) 
    { 
     MessageBox.Show(e.Message); 
    } 
}
