Getting file information from a file stored in a string

C#

Hello -

Here is what I have. A directory of files:

string[] filePaths = Directory.GetFiles(@"c:\files\", "*.*");


What I need to do is to use the File Signature to determine what the file type of each file is as I loop through, i.e. use the File Signature to determine if it's a .pdf (0xFFD8) or whatever.

Also I need to store the MD5 hash contents of each file as it is looping into a local variable.

I need to convert the file names stored in a string to actual files in order to glean this information.

How would I do this?

What I have tried:

not sure what to try - at a loss here
