Convert Image to Byte Array

May 10, 2013 at 1:30 AMAdmin

 

as the subject says ... if you want to convert an Image to an array of bytes to save it in the database or in a file or send it to a web service or another application , just put the following extension method in a static class and call it from the Image object like :


byte[] mImageBytes = img.ToBytes(ImageFormat.Png);

 

 

 

 

public static byte[] ToBytes(this Image image, ImageFormat format)

{

    if (image == null)

throw new ArgumentNullException("image");

    if (format == null)

throw new ArgumentNullException("format");

 

    using (MemoryStream stream = new MemoryStream())

    {

image.Save(stream, format);

return stream.ToArray();

    }

 

}
