How can I find the type of the file from the directory C#? I am reading the files from the directory and would like to find out if the file type is an image. Please let me know.

Thanks..

If fileInf is of type IO.FileInfo

System.IO.Path.GetExtension(fileInf.FullName)

or

fileInf.Extension

One way to determine the file type (presuming you dont just want to use the GetExtension() method) is to use File Magic Numbers, here and here.

TrIDNet has a great XML database of magic numbers.

how about this

string extension= System.IO.Path.GetExtension("s.jpeg"); if ((extension == ".jpeg") || (extension == ".jpg") || (extension == ".bmp")) { //true } else { //false }

If you get the extension, there should be a way to look up the file type registered to that extension in Windows. I'm not sure how to do the latter off hand.
