如何在windows phone 7的isolatedStorageDevice中導入一組現有的txt文件

Question

我有.txt中的17個文件，我想將所有這些文件導入到isolationStorageDevice。

我該怎麼做？

記住：我不想寫一個文件，我想把一個現有的文件在那裏。

的文件是在項目的文件夾中，例如：（/Files/user.txt）

手動

使用任何現有的Windows Phone獨立存儲資源管理器工具

你必須寫一個文件副本。假設有一個CordovaSourceDictionary.xml作爲項目的一部分，它指定哪些文件必須低於

StreamResourceInfo streamInfo = Application.GetResourceStream(new Uri("CordovaSourceDictionary.xml", UriKind.Relative)); 

if (streamInfo != null) 
{ 
    StreamReader sr = new StreamReader(streamInfo.Stream); 
    //This will Read Keys Collection for the xml file 

    XDocument document = XDocument.Parse(sr.ReadToEnd()); 

    var files = from results in document.Descendants("FilePath") 
       select new 
       { 
        path = (string)results.Attribute("Value") 
       }; 
    StreamResourceInfo fileResourceStreamInfo; 

    using (IsolatedStorageFile appStorage = IsolatedStorageFile.GetUserStoreForApplication()) 
    { 

     foreach (var file in files) 
     { 
      fileResourceStreamInfo = Application.GetResourceStream(new Uri(file.path, UriKind.Relative)); 

      if (fileResourceStreamInfo != null) 
      { 
       using (BinaryReader br = new BinaryReader(fileResourceStreamInfo.Stream)) 
       { 
        byte[] data = br.ReadBytes((int)fileResourceStreamInfo.Stream.Length); 

        string strBaseDir = AppRoot + file.path.Substring(0, file.path.LastIndexOf(System.IO.Path.DirectorySeparatorChar)); 

        if (!appStorage.DirectoryExists(strBaseDir)) 
        { 
         Debug.WriteLine("INFO: Creating Directory :: " + strBaseDir); 
         appStorage.CreateDirectory(strBaseDir); 
        } 

        // This will truncate/overwrite an existing file, or 
        using (IsolatedStorageFileStream outFile = appStorage.OpenFile(AppRoot + file.path, FileMode.Create)) 
        { 
         Debug.WriteLine("INFO: Writing data for " + AppRoot + file.path + " and length = " + data.Length); 
         using (var writer = new BinaryWriter(outFile)) 
         { 
          writer.Write(data); 
         } 
        } 
       } 
      } 
      else 
      { 
       Debug.WriteLine("ERROR: Failed to write file :: " + file.path + " did you forget to add it to the project?"); 
      } 
     } 
    } 
}
