DirectoryInfo

The following conditions may cause an exception:

  • The directory path is not valid for one of the following reasons: it is a zero-length string; it contains only white space; it contains invalid characters; or it is a device path (starts with \\.\) (ArgumentException).

  • The directory path is not valid because it is Nothing (ArgumentNullException).

  • The directory path exceeds the system-defined maximum length (PathTooLongException).

  • A file or directory name in the directory path contains a colon (:) or is in an invalid format (NotSupportedException).

  • The user lacks necessary permissions to view the directory path (SecurityException).

If the directory does not exist, an exception is not thrown until the first time a property on the DirectoryInfo object is accessed.
