예외 수정을위한 도움이 필요합니다.

Question

누군가 다음과 같은 2 가지 예외 상황을 설명 할 수 있습니까? 나는 그 문제를 해결 할 방법을 이해 드릴 수 없습니다 -

corex.dll 코드의 특정 조각이 ApplicationBarCallback :: 15 :: 요구시 작동

이다 ApplicationBarInterop 아래와 같이 발표 -

private void SaveButton_Click(object sender, EventArgs e) 
     { 
      WriteableBitmap wb = new WriteableBitmap(SelectedImage.TransformedImage); 
      MemoryStream targetStream = new MemoryStream(); 

      wb.SaveJpeg(targetStream, wb.PixelWidth, wb.PixelHeight, 0, 100); 

      if (targetStream != null) 
      { 
       targetStream.Seek(0, 0); // necessary to initiate the stream correctly before save 

       try 
       { 
        MediaLibrary ml = new MediaLibrary(); 
        Picture p = ml.SavePicture(Guid.NewGuid().ToString(), targetStream); 
        MessageBox.Show("Saved Successfully to your Media Library!"); 
       } 
       catch (Exception ex) 
       { 
        MessageBox.Show("Error - " + ex.Message); 
       } 
      } 
      else 
      { 
       MessageBox.Show("Unexpected error!"); 
      } 
     }

Answer 1

저장 버튼의 클릭 이벤트에 오류가 같은 몇 가지 코드를 추가 할 수 있지만 첫 번째 예외는 보이는하십시오

8 PhotoRotator.TransformedImage.SaveButton_Click 504 

시도가 단계별로 디버깅 할 수 있습니다. 몇 가지 코드를 알려주십시오.
