How to remove illegal characters from path and filenames?

Question

I need a robust and simple way to remove illegal path and file characters from a simple string. I\'ve used the below code but it doesn\'t seem to do anything, what am I miss

Answer 1

These are all great solutions, but they all rely on Path.GetInvalidFileNameChars, which may not be as reliable as you'd think. Notice the following remark in the MSDN documentation on Path.GetInvalidFileNameChars:

The array returned from this method is not guaranteed to contain the complete set of characters that are invalid in file and directory names. The full set of invalid characters can vary by file system. For example, on Windows-based desktop platforms, invalid path characters might include ASCII/Unicode characters 1 through 31, as well as quote ("), less than (<), greater than (>), pipe (|), backspace (\b), null (\0) and tab (\t).

It's not any better with Path.GetInvalidPathChars method. It contains the exact same remark.
