Error when Saving Screen from image to byteArray [duplicate]

I'm making a basic application that share screens. To do that I need to save the screen as a bitmap and then convert it to an array to be sent to the other client. But when I try to convert the Image to bytearray I get this error: "A generic error occurred in GDI+." Code:

        private void button1_Click(object sender, EventArgs e)          {              Bitmap bitmap = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height);              Graphics g = Graphics.FromImage(bitmap);              g.CopyFromScreen(0, 0, 0, 0, bitmap.Size);              Image I = GetCompressedBitmap(bitmap, 40);              byte[] Im = ImageToByteArray(I);              SendBytes(Im);            }            public byte[] ImageToByteArray(Image img)          {              try              {                  using (var stream = new MemoryStream())                  {                      img.Save(stream, System.Drawing.Imaging.ImageFormat.Png);                      return stream.ToArray();                  }              }              catch(Exception ex)              {                  Console.WriteLine(ex.ToString());                  return null;              }                        }            private Image GetCompressedBitmap(Bitmap bmp, long quality)          {              using (var mss = new MemoryStream())              {                  EncoderParameter qualityParam = new EncoderParameter(System.Drawing.Imaging.Encoder.Quality, quality);                  ImageCodecInfo imageCodec = ImageCodecInfo.GetImageEncoders().FirstOrDefault(o => o.FormatID == ImageFormat.Jpeg.Guid);                  EncoderParameters parameters = new EncoderParameters(1);                  parameters.Param[0] = qualityParam;                  bmp.Save(mss, imageCodec, parameters);                  return Image.FromStream(mss);              }          }  

Why does this occur and how can I solve this?
