Not applicable.



The access control to apply to the directory.

Exception typeCondition


The directory specified by path is read-only or is not empty.


The caller does not have the required permission.


path is a zero-length string, contains only white space, or contains one or more invalid characters as defined by InvalidPathChars.


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


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 is invalid, such as being on an unmapped drive.


Creating a directory with only the colon (:) character was attempted.


The directory specified by path is read-only or is not empty.

Use this method overload to create a directory with access control, so there is no chance the directory can be accessed before security is applied.

If the directory already exists, this method does nothing.
