◆ extension()
|
virtual |
Gets the extension part of the file name, including the leading dot . even if it is the entire file name, or an empty string if no extension is present.
- Returns
- A string containing the xtd::io::file_system_info extension.
- Remarks
- The Extension property returns the FileSystemInfo extension, which starts at, and includes, the last dot (.) in the file's full name. For example:
- For a file c:\NewFile.txt, this property returns ".txt".
- For a file c:.gitignore, this property returns ".gitignore".
- For a file c:\noextension, this property returns an empty string "".
- For a file c:.b.c, this property returns ".c".
- When the xtd::io::file_system_info is constructed from a file path with a trailing dot, then that trailing dot is trimmed, so new xtd::io::file_system_info("foo.bar.").extension returns ".bar".
