C# - Windows Phone 8.1 - StreamReader มันขึ้นเส้นหยักๆสีแดงตลอดเลยค่ะ ไม่รู้ผิดตรงไหน (มือใหม่)

System.IO.Stream src = Application.GetResourceStream(new Uri("/ProjectName;component/data/filename.txt", UriKind.Relative)).Stream;
using (StreamReader sr = new StreamReader(src))
{
	string text = sr.ReadToEnd();
}

   private string ReadFile(string filePath)
    {
        //this verse is loaded for the first time so fill it from the text file
        var ResrouceStream = Application.GetResourceStream(new Uri(filePath, UriKind.Relative));
        if (ResrouceStream != null)
        {
            Stream myFileStream = ResrouceStream.Stream;
            if (myFileStream.CanRead)
            {
                StreamReader myStreamReader = new StreamReader(myFileStream);

                //read the content here
                return myStreamReader.ReadToEnd();
            }
        }
        return "NULL";
    }

    String sFileReader = ReadFile("/ProjectName;component/data/filename.txt");

                        StorageFile f = await StorageFile.GetFileFromApplicationUriAsync(new Uri(@"ms-appx:///DataModel/my_file.txt"));
                        using (StreamReader tr = new StreamReader(await f.OpenStreamForReadAsync()))
                        {
                            foreach (var i in Enumerable.Range(1, 10))
                            {
                                s_tmp+= tr.ReadLine() + "\n\n";
                            }
                        }
