Public Methods

Method Description
Create ( Path path ) : void

Creates the specified directory.

Note: Unlike System.IO.Directory.CreateDirectory(System.String), this method only creates the last directory in path.

Delete ( Path path ) : void

Deletes the specified empty directory.
Delete ( Path path, bool recursively ) : void

Deletes files from the given path.
EnumerateDirectories ( Path path ) : IEnumerable

Returns a enumerable containing the directory names of the specified directory.
EnumerateDirectories ( Path path, string searchPattern ) : IEnumerable

Returns a enumerable containing the directory names of the specified directory that match the specified search pattern.
EnumerateFileSystemEntries ( Path path ) : IEnumerable

Returns a enumerable containing the file and directory names of the specified directory.
EnumerateFileSystemEntries ( Path path, string searchPattern ) : IEnumerable

Returns a enumerable containing the file and directory names of the specified directory that match the specified search pattern.
EnumerateFiles ( Path path ) : IEnumerable

Returns a enumerable containing the file names of the specified directory.
EnumerateFiles ( Path path, string searchPattern ) : IEnumerable

Returns a enumerable containing the file names of the specified directory that match the specified search pattern.
Exists ( Path path ) : bool

Returns a value indicating whether the specified path refers to an existing directory.

Note that this method will return false if any error occurs while trying to determine if the specified directory exists. This includes situations that would normally result in thrown exceptions including (but not limited to); passing in a directory name with invalid or too many characters, an I/O error such as a failing or missing disk, or if the caller does not have Windows or Code Access Security (CAS) permissions to to read the directory.

Method Details

Create() public static method

Creates the specified directory.
