Find image format using Bitmap object in C#

Question

I am loading the binary bytes of the image file hard drive and loading it into a Bitmap object. How do i find the image type[JPEG, PNG, BMP etc] from the Bitmap object?

Answer 1

Simply speaking you can't. The reason why is that Bitmap is a type of image in the same way that JPEG, PNG, etc are. Once you load a image into a Bitmap the image of the bitmap format. There is no way to look at a bitmap and understand the original encoding of the image (if it's even different than Bitmap).
