How to convert byte array to image file?

Question

I have browsed and uploaded a png/jpg file in my MVC web app. I have stored this file as byte[] in my database. Now I want to read and convert the byte[] to original file. How can i achieve this?

Answer 1

1. Create a MemoryStream passing the array in the constructor.
2. Read the image from the stream using Image.FromStream.
3. Call theImg.Save("theimage.jpg", ImageFormat.Jpeg).

Remember to reference System.Drawing.Imaging and use a using block for the stream.
