Text file encoding sample

Windows 8 store app에서 여러가지 작업을 하다가 접하는 문제 중에 하나가 파일을 읽어 들여서 사용해야 하는 경우에 Encodig문제가 발생한다. 그래서 간단하게 셈플을 만들었다.

(방법을 알면 정말 쉽게 할 수 있는데..모르면 정말..)

//ToArray()를 사용하기 위해 필요

    {
        public ItemDetailPage()

            this.InitializeComponent();

            //스크롤 뷰어 뷰 체인지 이벤트를 이용해서 위치 표시
            scrollViewer.ViewChanged +=
                (s, e) =>
                {
                    scrollPos.Text = scrollViewer.HorizontalOffset.ToString();
                };
        }

            FileOpenPicker openPicker = new FileOpenPicker();
            openPicker.ViewMode = PickerViewMode.List;
            openPicker.SuggestedStartLocation = PickerLocationId.Downloads;
            openPicker.FileTypeFilter.Add(".txt");
            //파일 하나 선택
            StorageFile file = await openPicker.PickSingleFileAsync();
            if (file != null)
            {
                //파일이 존재하면
                //내용을 버퍼에 읽어 들이고
                var buffer = await FileIO.ReadBufferAsync(file);
                //배열로 바꾸고
                var fileData = buffer.ToArray();
                //euc-Kr로 인코딩
                var encoding = Encoding.GetEncoding("euc-Kr");
                //파일명 출력
                title.Text = file.Name;
                //파일 패스 출력
                subtitle.Text = file.Path;
                //내용 출력
                var contents = encoding.GetString(fileData, 0, fileData.Length);
                textContent.Text = contents;
            }
        }
    }
