如何上傳選擇的圖像來解析對象？

Question

我要上傳，選擇照片來分析這裏對象 我們將選擇照片由galery

private void ChosePhoto_Click(object sender, RoutedEventArgs e) 
{ 
    CamerChoooserTask = new PhotoChooserTask(); 
    CamerChoooserTask.Completed += new EventHandler<PhotoResult>(CamerChoooserTask_Completed); 
     CamerChoooserTask.Show(); 
} 

private void CamerChoooserTask_Completed(object sender, PhotoResult e) 
{ 
    if (e.TaskResult == TaskResult.OK && e.ChosenPhoto != null) 
    { 
      imgto.Source = null; 
      MessageBox.Show(e.ChosenPhoto.Length.ToString()); 
      App.ChoosedImage = PictureDecoder.DecodeJpeg(e.ChosenPhoto); 
      imgto.Source = App.ChoosedImage; 
    } 
} 

.. 現在我們要Uplaod到對象

private async void UploadPhotoBtn_Click(object sender, RoutedEventArgs e) 
{ 
    // here I want to but my photo in array .. 
    byte[] data = System.Text.Encoding.UTF8.GetBytes("Working at Parse is great!"); 
    ParseFile file = new ParseFile("resume.txt", data); 

    var photo = new ParseObject("photo"); 
    photo["Photo"] = file; 
    await photo.SaveAsync(); 
} 

注：在解析的.Net指導文件是文本編碼 我想在這裏我需要將照片轉換爲二進制 我該怎麼辦？

Answer 1

要獲得從拍攝的照片的字節數組，你可以使用

byte[] postData = new byte[(int)e.ChosenPhoto.Length]; 
e.ChosenPhoto.Read(postData, 0, (int)e.ChosenPhoto.Length);
