I have many file types: pdf, tiff, jpeg, bmp. etc. My question is how can I change file extension? I tried this:

my file= c:/my documents/my images/cars/a.jp         


        

Answer 1

There is: Path.ChangeExtension method. E.g.:

var result = Path.ChangeExtension(myffile, ".jpg");

In the case if you also want to physically change the extension, you could use File.Move method:

File.Move(myffile, Path.ChangeExtension(myffile, ".jpg"));
