在仿真器C中测试漫游应用程序数据＃

Question

我正在使用Visual Studio 2017并尝试为Windows Phone编程C＃UWP应用程序。当我尝试在主机和模拟器（Mobile emulator 10.0.15063.0）之间测试漫游应用程序数据时，数据不会同步。即使等了几个小时。模拟器看起来像我的电子邮件和跨设备的日历同步一样工作。当我搜索主机上的文件，这似乎是正确创建：

C:\Users\Owner\AppData\Local\Packages\23840StartPoint.StartPointRunning_x6wjmepvaasdr\RoamingState 

我检查了包清单和包名和版本匹配。我尝试了几种不同的选择，但没有任何作用。我错过了什么。

来自GitHub的应用程序数据示例是我用来教导自己写/读文件的模型。它也不适用于我的设置。

var applicationData = ApplicationData.Current; 

ulong storage = applicationData.RoamingStorageQuota; 

//Create file client.txt => store data => Roaming folder 
ApplicationDataContainer roamingSettings = ApplicationData.Current.RoamingSettings; 

StorageFolder roamingFolder1 = ApplicationData.Current.RoamingFolder; 
StorageFile file1 = await roamingFolder1.CreateFileAsync(Filename1, CreationCollisionOption.ReplaceExisting); 

SetUpFlag = "true"; 
String string6 = Views.Colors101.m_BackGroundColor + ";" + Views.Colors101.m_CalendarColor + ";" + Views.Colors101.m_HeaderColor; 

String toWrite = SetUpFlag + ";" + string6; 

StorageFile xfile1 = await roamingFolder1.GetFileAsync(Filename1); 

await FileIO.WriteTextAsync(xfile1, toWrite); 

ApplicationData.Current.SignalDataChanged();

也许尝试我的版本，看看它是否效果更好..

const string _listofStuffFile = "allMyStuff.txt"; 
public static async Task<bool> SaveMyListData(List<string> saveData) 
    { 
     try 
     { 
      var savedStuffFile = await ApplicationData.Current.RoamingFolder.CreateFileAsync(_listofStuffFile, CreationCollisionOption.ReplaceExisting); 
      using (Stream ws = await savedStuffFile.OpenStreamForWriteAsync()) 
      { 
       var ss = new DataContractSerializer(typeof(List<string>)); 
       ss.WriteObject(ws, saveData); 
      } 
      return true; 
     } 
     catch { } 
     return false; 
    } 

public static async Task<List<string>> GetMyListData() 
    { 
     try 
     { 
      var rs = await ApplicationData.Current.RoamingFolder.OpenStreamForReadAsync(_listofStuffFile); 
      if (rs == null) 
       return new List<string>(); 
      var ss = new DataContractSerializer(typeof(List<string>)); 
      var sr = (List<string>)ss.ReadObject(rs); 
      return sr; 
     } 
     catch { } 
     return new List<string>(); 
    }
