Example 1: bitmap to byte array c#

public static byte[] ImageToByteArray(Image img)
        {
            using (var stream = new MemoryStream())
            {
                img.Save(stream, System.Drawing.Imaging.ImageFormat.Png);
                return stream.ToArray();
            }
        }

Example 2: c# byte array to bitmap

Bitmap bmp;
using (var ms = new MemoryStream(imageData))
{
    bmp = new Bitmap(ms);
}

Example 3: c# bitmap to array byte

public static class ImageExtensions
{
    public static byte[] ToByteArray(this Image image, ImageFormat format)
    {
        using(MemoryStream ms = new MemoryStream())
        {
            image.Save(ms, format);
            return ms.ToArray();
        }
