將IsolatedStorageFileStream從Windows phone 8.1轉換爲Windows 8.1

我在windows phone應用程序中編寫了此代碼以便從xml文件讀取和寫入數據，並且工作正常。，所以我想在Windows 8.1中的應用程序使用它，但它沒有工作，我如何將其轉換爲與Windows 8.1將IsolatedStorageFileStream從Windows phone 8.1轉換爲Windows 8.1

public void Read(string strXMLFile) 
    { 
     IsolatedStorageFile isfData = IsolatedStorageFile.GetUserStoreForApplication(); 
     XDocument doc = null; 
     IsolatedStorageFileStream isfStream = null; 
     if (isfData.FileExists(strXMLFile)) 
     { 
      isfStream = new IsolatedStorageFileStream(strXMLFile, FileMode.Open, isfData); 
      doc = XDocument.Load(isfStream); 
      isfStream.Close(); 
     } 
     else 
     { 
      doc = XDocument.Load(strXMLFile); 
      isfStream = new IsolatedStorageFileStream(strXMLFile, FileMode.CreateNew, isfData); 
      doc.Save(isfStream); 
      isfStream.Close(); 
     } 

     var vData = from s in doc.Descendants("Row") select new ColData(s); 
    } 


    public void Write(string strXMLFile) 
    { 
     XElement xml = new XElement("Tabel", 
         from p in this 
         select p.Information); 

     IsolatedStorageFileStream isfStream = new IsolatedStorageFileStream(strXMLFile, FileMode.Open, IsolatedStorageFile.GetUserStoreForApplication()); 
     xml.Save(isfStream); 
     isfStream.Close(); 

    }

你究竟是什麼意思，但「不起作用」？ – 2014-11-09 13:25:23

我的意思是這個代碼適用於Windows Phone 8.1應用程序，但不適用於Windows 8.1應用程序或Windows RT應用程序 – masalahi 2014-11-09 13:32:45

是的，但是定義什麼不起作用。拋出異常？代碼掛起？究竟是什麼？ – 2014-11-09 13:34:26

您需要使用新的API，以讀取文件兼容

var file = await localFolder.GetFileAsync("dataFile.txt"); 
var data = await FileIO.ReadTextAsync(file);

和寫入

var file = await localFolder.CreateFileAsync("dataFile.txt",  CreateCollisionOption.ReplaceExisting); 
await FileIO.WriteTextAsync(file , "data");
