emgu 캡처 한 이미지를 MySQL 데이터베이스에 저장

Question

emgu 이미지 형식을 바이트 문자열로 변환 할 수 있으며이 코드로 MySQL 데이터베이스에 저장되지만 이미지는 인식되지 않는 형식으로 저장됩니다. 나는 내가 fs = new FileStream(named, FileMode.Open, FileAccess.Read); 줄에 system not supported 예외가 최종 이미지의 서식을 추가 할 때 창 이미지 뷰어에 의해

  string myConnection = mydbconnection; 

      MySqlConnection myConn = new MySqlConnection(myConnection); 

      myConn.Open(); 

      Bitmap image = trained.ToBitmap(); 

      MemoryStream ms = new MemoryStream(); 

      image.Save(ms, System.Drawing.Imaging.ImageFormat.Bmp); 

      byte[] picture = ms.ToArray(); 

      string formmattedPic = Convert.ToBase64String(picture); 

      MySqlCommand cmd = new MySqlCommand("INSERT INTO sql434250.facialid (timeanddate,photo1) VALUES(@named,@Trainedface)",myConn); 

      cmd.Parameters.Add("@named", MySqlDbType.VarChar).Value = named; 
      cmd.Parameters.Add("@Trainedface", MySqlDbType.Blob); 
      cmd.Parameters["@Trainedface"].Value = formmattedPic; 


        cmd.ExecuteNonQuery(); 

        label4.Text = named.ToString(); 

        myConn.Close(); 
       } 

내 문제는 내가 (C#을 새로운)를 파일 스트림 작품, 그래서 용서하시기 바랍니다 방법 확실하지 않다, 시작 코드에있는 모든 명백한 실수에 대한 정보, 윈도우 8 OS, 2013에 대 한있어

여기에 :

  FileStream fs; 

      BinaryReader br; 


     byte[] ImageData; 



     **fs = new FileStream(named, FileMode.Open, FileAccess.Read);** 

     br = new BinaryReader(fs); 

     ImageData = br.ReadBytes((int)fs.Length); 

     br.Close(); 

     fs.Close(); 




      MySqlCommand cmd = new MySqlCommand("INSERT INTO sql434250.facialid (timeanddate,photo1) VALUES(@named,@Trainedface)",myConn); 

      cmd.Parameters.Add("@named", MySqlDbType.VarChar).Value = named; 
      cmd.Parameters.Add("@Trainedface", MySqlDbType.Blob); 
      cmd.Parameters["@Trainedface"].Value = ImageData; 


        cmd.ExecuteNonQuery(); 

나는 내 PC에 저장된 변환 된 이미지를 가지고 내 부끄러움을 나는 그것의 코딩 오류 알 수 있도록 수동으로 MySQL의 사이트를 통해 이러한 이미지는 소프트웨어와 함께 작동합니까 이미지를 다운로드 할 수 있어요.

내가, 내가 뭘 잘못했는지 모르겠어요 내 질문을 해결할 수있었습니다을 추가하지만 조금 복사하여 다음과 같이

는 데이터베이스 테이블을 추가 여기 저기에 다음 코드가 작동합니다. 내가 한 것은 이미지를 로컬 응용 프로그램 파일에 저장 한 다음이 파일 위치를 파일 스트림에 사용하는 것입니다.

   named = DateTime.Now.ToString("dd-MM-yy HH:mm:ss:ms"); 
      TrainedFace.Save(Application.StartupPath + "/Temp/face1.bmp"); 

      string dated = DateTime.Now.ToString("HH:mm:ss:ff dd-MM-yy"); 
      label4.Text = dated; 

      //Show face added in gray scale 
      imageBox1.Image = TrainedFace; 
      trainingImages.Add(TrainedFace); 
      labels.Add(label4.Text); 

      byte[] imagepic = null; 
      FileStream fsstream = new FileStream(Application.StartupPath + "/Temp/face1.bmp", FileMode.Open, FileAccess.Read); 
      BinaryReader br = new BinaryReader(fsstream); 
      imagepic = br.ReadBytes((int)fsstream.Length); 

      string myConnection = "datasource=sql4.freemysqlhosting.net;port=3306;user=sql434250;password=lE3!lQ5*";

      MySqlDataReader myReader; 

       myConn.Open(); 
       SelectCommand.Parameters.Add(new MySqlParameter("@IMG", imagepic));
