title: Size of bitmap byte[] differs from BMP memorystream size
body: <p>I´m trying to send a bitmap over a tcp/ip connection. So far my programm works as it should. But during debugging I discovered a strange value of my bitmap byte[].</p>
  
  <p>I open a 24bit bitmap and convert it to 16bit. The bitmap is 800x600 so the byte[] length should be 800*800*2Byte = 960000Byte... But my array is 960054...</p>
  
  <p>Where do the extra Bytes come from??</p>
  
  <pre><code>        Console.WriteLine("Bitmap auf 16Bit anpassen...\n");
          Rectangle r = new Rectangle(0,0,bitmap_o.Width, bitmap_o.Height);
          Bitmap bitmap_n = bitmap_o.Clone(r, PixelFormat.Format16bppRgb555);
          bitmap_n.Save("test2.bmp");
  
          Console.WriteLine("Neue Bitmap-Eigenschaften:");
          Console.WriteLine(bitmap_n.Width.ToString());
          Console.WriteLine(bitmap_n.Height.ToString());
          Console.WriteLine(bitmap_n.PixelFormat.ToString());
  
          byte[] data = new byte[0];
          MemoryStream mem_stream = new MemoryStream();
          bitmap_n.Save(mem_stream, ImageFormat.Bmp);
          data = mem_stream.ToArray();
          mem_stream.Close();
  
          Console.WriteLine(data.Length.ToString());
  
          stream.Write(data, 0, 960000);
          Console.WriteLine("Sending data...");
