title: Check ISO is valid or not
body: <p>Is there any C# way to check an ISO file is valid or not i.e. valid Iso format or any other check possible or not.
  The scenario is like, if any text file(or any other format file) is renamed to ISO and given it for further processing. I want to check weather this ISO file is a valid ISO file or not? Is there any way exist programmatically like to check any property of the file or file header or any other things </p>
