To count differences within a file can become quite complex if you want to do it properly, and as far as I know .NET does not have anything built in to do this. In my opinion, what you need is a <strong>Difference</strong> (or <strong>Diff</strong>) <strong>algorithm</strong>. Do a Google search for <em>'diff algorithm'</em> and you should find plenty of examples and free classes you can use in your code. :) Thanks for your comment Pankaj.

I absolutely agree that hashing is the best way to compare files. Thanks for your comment Robert. I absolutely agree that hashing is the best way to compare files.

Using the created or last modified date properties of the FileInfo class tend to be inaccurate, and file sizes can still be equivalent when a single ascii character changes value, so hashing in my opinion is by far the best way to compare files for equality.
