The security to apply.

Return Value

The last directory specified in path.
Exception typeCondition

ArgumentException

path does not specify a valid file path or contains invalid DirectoryInfo characters.

ArgumentNullException

path is a null reference (Nothing in Visual Basic).

DirectoryNotFoundException

The specified path is invalid, such as being on an unmapped drive.

IOException

The subdirectory cannot be created.

-or-

A file or directory already has the name specified by path.

PathTooLongException

The specified path, file name, or both exceed the system-defined maximum length. For example, on Windows-based platforms, paths must be less than 248 characters, and file names must be less than 260 characters. The specified path, file name, or both are too long.

SecurityException

The caller does not have code access permission to create the directory.

-or-

The caller does not have code access permission to read the directory described by the returned DirectoryInfo object. This can occur when the path parameter describes an existing directory.

NotSupportedException

path contains a colon character (:) that is not part of a drive label ("C:\").

Any and all directories specified in path are created, unless some part of path is invalid. The path parameter specifies a directory path, not a file path. If the subdirectory already exists, this method does nothing.

NoteNote:

Path names are limited to 248 characters.
