To convert a JPG file to a BMP file in C#, you can use the System.Drawing namespace.
This code loads the JPG image from disk, creates a new Bitmap object with the same dimensions, draws the JPG image onto the Bitmap, and then saves the Bitmap as a BMP file. Note that you will need to add using System.Drawing.Imaging; at the top of your file to use the ImageFormat.Bmp constant.
