[wp8] wp8에서 파일 읽고 쓰기

 

일단 저장부터 ㅋ

private async Task FileSave(MemoryStream stream)

     {

         IStorageFolder applicationFolder = ApplicationData.Current.LocalFolder;

         IStorageFile storageFile = await applicationFolder.CreateFileAsync(Const.LocalPlaylistFileName, CreationCollisionOption.ReplaceExisting);

         using (Stream fileStream = await storageFile.OpenStreamForWriteAsync())

         {                

             stream.Seek(0, SeekOrigin.Begin);

             await stream.CopyToAsync(fileStream);

             await fileStream.FlushAsync();

             stream.Dispose();

         }

 

로드하는부분

public async Task LoadAlbums()

       {

           IStorageFolder applicationFolder = ApplicationData.Current.LocalFolder;

           IStorageFile storageFile = await applicationFolder.GetFileAsync(Const.LocalPlaylistFileName);

           IRandomAccessStream accessStream = await storageFile.OpenReadAsync();

           using (Stream stream = accessStream.AsStreamForRead((int)accessStream.Size))

           {

               var o = _serializer.ReadObject(stream);

               LocalPlaylist = o as ObservableCollection<LocalMyAlbum>;

           }

       }

 

일단 윈7이랑 조금 달라졌다.

 

참조한곳이랑은 약간 다르게 구현~
