将图像保存为c＃中图形对象的byte []

Question

I will get image in byte from database and using system.drawing.graphic to add some necessary stuff , and after this i need to save this image in byte[] and send to front end (silver light 4) to print.

note(I am not going to save this in physical file).

I appreciate every help or you guys and provide example code if possible.

Answer 1

byte[] result;
using (Image newImage = new Bitmap(origImage))
{
    using (Graphics graphics = Graphics.FromImage(newImage))
    {
        // do some drawing
    }

    using (MemoryStream ms = new MemoryStream())
    {
        newImage.Save(ms, ImageFormat.Png);
        result = ms.ToArray();
    }
}

To restore the image from the byte[] :

Image restored = Image.FromStream(new MemoryStream(result));
